Abstract
There is no consensus as to the optimal skeletal fixation method for Gustilo-Anderson IIIb fractures. External fixation methods have previously shown higher rates of superficial infection, whilst internal fixation has shown higher risk of deep infection, but lower risk of other complications. This paper investigates outcomes in open tibial fractures based on fixation method. A retrospective review was performed for patients presenting to an ortho-plastic unit with GA IIIb tibial fractures between June 2013 and October 2021. 85 patients were identified. The most common implant was an intramedullary nail (IMN), used in 29 patients (34.1%); open reduction and internal fixation (ORIF) was performed in 16 patients (18.8%). 18 patients (21.2%) were definitively managed with a frame alone. Mean follow-up from was 18 months (2-77). Patients with ORIF needed a mean of 3.37 operations; it was 2.48 for IMN which was significantly different from frames at 5.00 (p=0.000). The mean time to bony union after definitive fixation was 11.4 months. This differed depending on the implant used for fixation, with ORIF at 7.1 months, 10.1 for IMN, and frames at 17.2 months; ORIF significantly differed from frames (p=0.009). Superficial infection was common, seen in 38.8% of patients, and only 3 patients (4%) developed deep infections involving metalwork, with no difference in rates of either based on fixation method This study supports that ORIF has faster healing times, with less time to union compared to frames. It also shows that no implant was superior to another in terms of outcomes.

Abstract
AIMS Global guidelines recommend that all older patients with cancer receiving chemotherapy should undergo a geriatric assessment. However, utilisation of the geriatric assessment is often constrained by its time-intensive nature, which limits its adoption in settings with limited resources and high demand. There is a lack of evidence correlating the results of the geriatric assessment with survival from the Indian subcontinent. Therefore, the aims of the present study were to assess the impact of the geriatric assessment on survival in older Indian patients with cancer and to identify the factors associated with survival in these older patients. MATERIALS AND METHODS This was an observational study, conducted in the geriatric oncology clinic of the Tata Memorial Hospital (Mumbai, India). Patients aged 60 years and older with cancer who underwent a geriatric assessment were enrolled. We assessed the non-oncological geriatric domains of function and falls, nutrition, comorbidities, cognition, psychology, social support and medications. Patients exhibiting impairment in two or more domains were classified as frail. RESULTS Between June 2018 and January 2022, we enrolled 897 patients. The median age was 69 (interquartile range 65-73) years. The common malignancies were lung (40.5%), oesophagus (31.9%) and genitourinary (12.1%); 54.6% had metastatic disease. Based on the results of the geriatric assessment, 767 (85.4%) patients were frail. The estimated median overall survival in fit patients was 24.3 (95% confidence interval 18.2-not reached) months, compared with 11.2 (10.1-12.8) months in frail patients (hazard ratio 0.54; 95% confidence interval 0.41-0.72, P < 0.001). This difference in overall survival remained significant after adjusting for age, sex, primary tumour and metastatic status (hazard ratio 0.56; 95% confidence interval 0.41-0.74, P < 0.001). In the patients with a performance status of 0 or 1 (n = 454), 365 (80.4%) were frail; the median overall survival in the performance status 0-1 group was 33.0 months (95% confidence interval 24.31-not reached) in the fit group versus 14.4 months (95% confidence interval 12.25-18.73) in the frail patients (hazard ratio 0.50; 95% confidence interval 0.34-0.74, P = 0.001). In the multivariate analysis, the geriatric assessment domains that were predictive of survival were function (hazard ratio 0.68; 95% confidence interval 0.52-0.88; P = 0.003), nutrition (hazard ratio 0.64; 95% confidence interval 0.48-0.85, P = 0.002) and cognition (hazard ratio 0.67; 95% confidence interval 0.49-0.91, P = 0.011). DISCUSSION The geriatric assessment is a powerful prognostic tool for survival among older Indian patients with cancer. The geriatric assessment is prognostic even in the cohort of patients thought to be the fittest, i.e. performance status 0 and 1. Our study re-emphasises the critical importance of the geriatric assessment in all older patients planned for cancer-directed therapy.

Abstract
Abstract
Background
2-dimensional transesophageal echocardiography (2D-TEE) and balloon sizing are commonly used for assessment of Ostium secundum atrial septal defect (OS-ASD) prior to device closure but complications do occur. Therefore, assessment of accurate morphology and anatomy of the defect in three-dimensional plane is essential for transcatheter device closure to be successful, which the 2D TEE fails to reveal.
Purpose
2D TEE has long been used to decide size of the device required for transcatheter closure of OS-ASD and the appropriate candidates. However, complications like inadequate closure, leaving behind residual defect or device embolization often come into picture. The reason behind this is complex anatomy of some defects in the three-dimensional plane. Purpose of this study was to see if the routine use of 3D zoom with 2D TEE can better help to select the appropriate patients for device closure than that by 2 TEE alone.
Methods
We enrolled 71 OS-ASD patients from October 2020 to December 2021. All the patients underwent transesophageal echocardiography (TEE). Assessment of quantitative (number, shape and size of defect and size of residual rims) and qualitative (aneurysm, malalignment, fenestration) parameters was done by both 2D and 3D zoom. The measurements by 2D and 3D TEE clips were done by different operators. Transcatheter device closure was done for the patients with defect morphology and residual rims amenable for the same, with acceptable pulmonary pressure. Patients found to be adequate for the device closure by 2D TEE, when further found to have an unfavorable morphology by 3D TEE, were referred for surgical management. Follow up transthoracic echo was done after 1 month.
Results
Of the 71 patients, 65% were females and mean age was 26.23±10.75 years. By 3D TEE, 66% had circular defect,19% had oval defect and 14% had complex defect. 2 patients had spiral defect. Malalignment of the septum was seen in 4 (5.6%) patients by 2D TEE whereas in 13 (18.3%) patients by 3D TEE. Septal aneurysm was seen in 1 (1.4%) by 2D TEE whereas in 3 (4.2%) patients by 3D TEE. Mean largest size obtained by 2D was 24.82±9 mm and that by 3D was 26.23±8.42. By 3D TEE, 37 patients had at least one rim deficient (<5 mm). 3D Maximal diameter strongly correlated with 2D Maximal diameter (correlation coefficient 0.860; p<0.01). 9 (12.6%) patients found adequate for the device closure by 2D TEE were further found to have an unfavorable morphology by 3D TEE. 38 (53.5%) patients underwent device closure and 20 (28.2%) patients underwent surgical patch closure. At 1 month follow up all the 38 patients had device in-situ and had no residual shunt.
Conclusions
In OS-ASD patients, routine use of 3D zoom modality can complement 2D TEE in deciding appropriate patients for transcatheter device closure and help prevent many unforeseeable complications.

Abstract
Co-occurrent KRAS and TP53 mutations define a majority of patients with pancreatic ductal adenocarcinoma (PDAC) and define its pro-metastatic proclivity. Here, we demonstrate that KRAS-TP53 co-alteration is associated with worse survival compared with either KRAS-alone or TP53-alone altered PDAC in 245 patients with metastatic disease treated at a tertiary referral cancer center, and validate this observation in two independent molecularly annotated datasets. Compared with non-TP53 mutated KRAS-altered tumors, KRAS-TP53 co-alteration engenders disproportionately innate immune-enriched and CD8+ T-cell-excluded immune signatures. Leveraging in silico, in vitro, and in vivo models of human and murine PDAC, we discover a novel intersection between KRAS-TP53 co-altered transcriptomes, TP63-defined squamous trans-differentiation, and myeloid-cell migration into the tumor microenvironment. Comparison of single-cell transcriptomes between KRAS-TP53 co-altered and KRAS-altered/TP53WT tumors revealed cancer cell-autonomous transcriptional programs that orchestrate innate immune trafficking and function. Moreover, we uncover granulocyte-derived inflammasome activation and TNF signaling as putative paracrine mediators of innate immunoregulatory transcriptional programs in KRAS-TP53 co-altered PDAC. Immune subtyping of KRAS-TP53 co-altered PDAC reveals conflation of intratumor heterogeneity with progenitor-like stemness properties. Coalescing these distinct molecular characteristics into a KRAS-TP53 co-altered "immunoregulatory program" predicts chemoresistance in metastatic PDAC patients enrolled in the COMPASS trial, as well as worse overall survival.

Abstract
The "leaky pipeline" of women in science, technology, engineering, and mathematics (STEM), which is especially acute for academic mothers, continues to be problematic as women face continuous cycles of barriers and obstacles to advancing further in their fields. The severity and prevalence of the COVID-19 pandemic both highlighted and exacerbated the unique challenges faced by female graduate students, postdocs, research staff, and principal investigators because of lockdowns, quarantines, school closures, lack of external childcare, and heightened family responsibilities, on top of professional responsibilities. This perspective provides recommendations of specific policies and practices that combat stigmas faced by women in STEM and can help them retain their careers. We discuss actions that can be taken to support women within academic institutions, journals, government/federal centers, university-level departments, and individual research groups. These recommendations are based on prior initiatives that have been successful in having a positive impact on gender equity─a central tenet of our postpandemic vision for the STEM workforce.

Abstract
Abstract
Background
Management of traumatic bone void associated with Gustilo IIIB open fractures is challenging. Gentamicin eluting synthetic bone graft substitute (Cerament-G) had been recently utilised for the management of patients with these injuries. This study aims to assess radiological signs of Cerament-G remodelling.
Method
Retrospective data analysis of all patients admitted to our unit with IIIB open fractures who had Cerament-G applied as avoid filler. Postoperative radiographic images of the fracture site at 6-weeks, 3-months, 6-months and at the last follow-up were reviewed. The radiological signs of Cerament-G integration, percent of void healing, and bone cortical thickness at the final follow-up were assessed.
Results
34 patients met our inclusion criteria, mean age: 42 years. Mean follow-up time was 20 months. 59% of patients had excellent (>90%) void filling, 26.4% of patients had 50-90% void filling, and 14.6% had < 50% void filling. Normal bone cortical thickness was restored on AP and Lateral views in 55.8% of patients. No residual Cerement-G was seen on X-rays at the final follow-up in any of the patients.
Conclusions
Our results showed successful integration of Cerament-G with excellent void filling and normal cortical thickness achieved in more than half of the patients.

Abstract
Abstract
Background
Non-tuberculous pyogenic spinal infection (PSI) incorporates a variety of different clinical conditions. Surgical interventions may be necessary for severe cases where there is evidence of spinal instability or neurological compromise. The primary surgical procedure focuses on the anterior approach with aggressive debridement of the infected tissue regions. We aim to evaluate the effectiveness of the posterior approach without debridement.
Method
Several databases including MEDLINE, NHS evidence and the Cochrane database were searched. The main clinical outcomes evaluated include pain, neurological recovery (Frankel Grading System, FGS) post-operative complications and functional outcomes (Kirkaldy-Willis Criteria and Spine Tango Combined Outcome Measure Index, COMI).
Results
From the four papers included in the meta-analysis, post-operative pain levels were found to be lower at a statistically significant level when a random effects model was applied, with the effect size found to be at 0.872 (p < 0.001, 95% CI: 0.7137 to 1.0308). Post-surgical neurological improvement was also demonstrated with a mean FGS improvement of 1.12 in 64 patients over the included articles.
Conclusions
Posterior approach with posterior stabilisation without formal debridement can results in successful infection resolution, improved pain scores and neurological outcomes. However, Larger series with longer follow-up duration are strongly recommended.

Abstract
Background:Patients with rheumatological foot disease are an overlooked population, and it was noted locally that these patients received a fragmented service; attending multiple appointments for the management of one clinical issue. This led to delays in treatment; significant inter-departmental correspondence and variations in the peri-operative management of disease modifying anti-rheumatic drug (DMARD) and biologic therapies. To remedy this a foot multidisciplinary (MDT) clinic was established, including input from rheumatology, orthopaedic surgery, specialist rheumatology podiatry and physiotherapy. The outcomes from the foot MDT clinic have been analysed in this service evaluation project.Objectives:To evaluate the outcomes of the multidisciplinary foot MDT clinic, with particular reference to concordance to the British Rheumatology Society (BSR) guidelines on peri-operative medicine guidelines.Methods:Data was collected retrospectively across all clinics from January 2017 to February 2019. Clinic letters were obtained, and data was collected using a standardised data collection sheet. Data was collected on patient demographics, rheumatological diagnoses, treatment outcomes from the foot MDT, appropriateness of peri-operative plan and post-operative complications. No data was available on these outcomes prior to the advent of the foot MDT clinic.Results:Data from 12 clinics was analysed (n=40). Patients had a median age of 66 years (IQR 27.5 years); 65% of patients were female and 35% of patients were male. The commonest rheumatological foot disease seen was rheumatoid arthritis (67%), followed by psoriatic arthritis (15%). All patients were treated with biologic or non-biologic DMARDs. Treatment outcomes were as follows: 27.5% were offered surgical treatment; 10% were offered intra-articular (IA) injections under ultrasound guidance; 10% were offered IA injections under general anaesthetic; 25% underwent specialist rheumatology podiatry, and the remaining 30% elected for a conservative approach after careful consideration of treatment options. Of those who were offered surgical treatment, 72% of patients were provided with a peri-operative plan which accorded with British Rheumatology Society (BSR) guidelines. Of those whom underwent surgery, one patient’s surgical treatment was complicated by a post-operative infection; however, the peri-operative DMARD/biologic plan was not felt to be contributing factor.Conclusion:The foot MDT clinic provides a comprehensive review of rheumatological foot conditions, with readily available access to a full range of treatment options. Co-location of all relevant professionals allows for real-time interdepartmental communication; shared decision making between clinicians and patients; avoids multiple appointments; reduces uncertainty with peri-operative planning as well as providing a cost-effective and efficacious service. Discrepancies in the peri-operative plan for medicines arose when the treating orthopaedic surgeon was not present in clinic. In these cases, the plan for surgical treatment was made outside of this clinic, without input from the treating rheumatologist. To improve concordance with BSR peri-operative medicine guidelines, it is recommended that all treatment decisions are made during the clinic, allowing input from all relevant partners. Informal feedback from patients commended the foot MDT, this shall be formalised through further qualitative data.Disclosure of Interests:None declared

Abstract
We investigated the strength of commonly used spinal needles in relation to the amount of deformation, and registered forces during standardised testing. We investigated differences between manufacturers for the same length and gauge of Luer and non-Luer needles, and examined the effect of the internal stylet in terms of needle strength. A specialised rig was designed to perform the testing in both the horizontal and axial plane, reflecting common industrial tests and clinical use. Needles from four commonly used manufacturers were used (Vygon, Becton Dickinson, B Braun, and Pajunk). Needles of 25 G and 27 G were tested in 90-mm and 120-mm lengths. We found significant differences in terms of the size of final deformation and 'toughness'/resistance to deformation between needles of different brands. There were also significant differences between horizontal tests conducted as an industry standard and our own axial test. This may have bearing on clinical use in terms of the incidence of bending and breakage. The presence of the internal stylet resulted in significantly greater toughness in many needles, but had little effect on the degree of deformation. Comparison of Luer and non-Luer needles of the same brand and size showed few significant differences in strength. This result is reassuring, given the imminent change from Luer to non-Luer needles that is to occur in the UK.

Abstract
Only 2 major mast cell (MC) subtypes are commonly recognized in the mouse: the large connective tissue mast cells (CTMCs) and the mucosal mast cells (MMCs). Interepithelial mucosal inflammatory cells, most commonly identified as globule leukocytes (GLs), represent a third MC subtype in mice, which we term interepithelial mucosal mast cells (ieMMCs). This term clearly distinguishes ieMMCs from lamina proprial MMCs (lpMMCs) while clearly communicating their common MC lineage. Both lpMMCs and ieMMCs are rare in normal mouse intestinal mucosa, but increased numbers of ieMMCs are seen as part of type 2 immune responses to intestinal helminth infections and in food allergies. Interestingly, we found that increased ieMMCs were consistently associated with decreased mucosal inflammation and damage, suggesting that they might have a role in controlling helminth-induced immunopathology. We also found that ieMMC hyperplasia can develop in the absence of helminth infections, for example, in Treg-deficient mice, Arf null mice, some nude mice, and certain graft-vs-host responses. Since tuft cell hyperplasia plays a critical role in type 2 immune responses to intestinal helminths, we looked for (but did not find) any direct relationship between ieMMC and tuft cell numbers in the intestinal mucosa. Much remains to be learned about the differing functions of ieMMCs and lpMMCs in the intestinal mucosa, but an essential step in deciphering their roles in mucosal immune responses will be to apply immunohistochemistry methods to consistently and accurately identify them in tissue sections.
