Abstract
BACKGROUND Diagnosis of bacterial meningitis remains a challenge in most developing countries due to low yield from bacterial culture, widespread use of non-prescription antibiotics, and weak microbiology laboratories. The objective of this study was to compare the yield from standard bacterial culture with the multiplex nested PCR platform, the BioFire® FilmArray® Meningitis/Encephalitis Panel (BioFire ME Panel), for cases with suspected acute bacterial meningitis. METHODS Following Gram stain and bacterial culture on cerebrospinal fluid (CSF) collected from children aged less than 5 years with a clinical suspicion of acute bacterial meningitis (ABM) as defined by the WHO guidelines, residual CSF specimens were frozen and later tested by BioFire ME Panel. RESULTS A total of 400 samples were analyzed. Thirty-two [32/400 (8%)] of the specimens were culture positive, consisting of; three Salmonella spp. (2 Typhi and 1 non-typhi), three alpha hemolytic Streptococcus, one Staphylococcus aureus, six Neisseria meningitidis, seven Hemophilus influenzae, 11 Streptococcus pneumoniae and 368 were culture negative. Of the 368 culture-negative specimens, the BioFire ME Panel detected at least one bacterial pathogen in 90 (24.5%) samples, consisting of S. pneumoniae, N. meningitidis and H. influenzae, predominantly. All culture positive specimens for H. influenzae, N. meningitidis and S. pneumoniae also tested positive with the BioFire ME Panel. In addition, 12 specimens had mixed bacterial pathogens identified. For the first time in this setting, we have data on the viral agents associated with meningitis. Single viral agents were detected in 11 (2.8%) samples while co-detections with bacterial agents or other viruses occurred in 23 (5.8%) of the samples. CONCLUSIONS The BioFire® ME Panel was more sensitive and rapid than culture for detecting bacterial pathogens in CSF. The BioFire® ME Panel also provided for the first time, the diagnosis of viral etiologic agents that are associated with meningoencephalitis in this setting. Institution of PCR diagnostics is recommended as a routine test for suspected cases of ABM to enhance early diagnosis and optimal treatment.

Abstract
Sc1 is a high-prevalence blood group antigen that is part of the Scianna blood group system. The clinical significance of Scianna antibodies is not well understood because of their rarity; there are only a handful of cases in the literature. This scarcity of information can make it difficult to decide on the best course of action when transfusing a patient with alloantibodies to Scianna blood group antigens. We describe a case of an 85-year-old woman presenting with melena and a hemoglobin of 66 g/L. Upon request for crossmatched blood, a panreactive antibody was found, later elucidated to be alloanti-Sc1. Because of the urgent nature of the transfusion, the patient was transfused with 2 incompatible, presumed Sc1+, red blood cell units with no evidence of an acute or delayed transfusion reaction. This case has been shared with the International Society of Blood Transfusion Rare Donor Working Party, via their Outcome of Incompatible Transfusion form, and adds to the body of evidence on clinical significance of antibodies to the antigens of the Scianna blood group system.

Abstract
AIMS To generate utility decrements for three attributes associated with catheterisation for individuals with a spinal cord injury (SCI): the process of catheterisation, the physical impact of urinary tract infections (UTIs) and worry associated with hospitalisation. MATERIALS AND METHODS Health state vignettes comprising various levels of the three attributes were developed. Two cohorts of respondents, corresponding to people with SCIs and a sample broadly representative of the UK population, were presented with nine vignettes (three vignettes for the mild, moderate and severe health states in addition to a random set of six vignettes). It was assumed no or a nominal decrement was associated with the mild health state. Utility decrements were derived from analysing the data obtained from the online time trade-off (TTO). A proportion of the SCI cohort (n = 57) also completed the EQ-5D-5L questionnaire. RESULTS Utility decrements were generated using statistical models for the general population (n = 358), the SCI population (n = 48) and the two populations combined (merged model, n = 406). Results from the two cohorts showed minimal differences. For the merged model, SCI status was not statistically significant. All interaction terms, excluding SCI and the severe level of the physical attribute, were not statistically significant. Compared to the mild level, the greatest utility decrement calculated was the severe level of the emotional (worry) attribute (0.09, p < 0.001) for the SCI population. A significant decrement of 0.02 (p <0.001) was calculated for the moderate level of the emotional attribute for all models. The mean utility score for those with SCI having completed the EQ-5D-5L was 0.371. LIMITATIONS Modest sample size of respondents from the SCI population (n = 48). CONCLUSIONS Worry associated with hospitalisation had the greatest impact on patients' health-related quality of life (HRQoL). The catheterisation process, such as the lubrication and repositioning of the catheter, also impacted on patients' HRQoL.

Abstract
This study outlines two novel protocols for examining context specific recall in animals prior to embarking on neurobiological studies. The approach is distinct from and contrasts with studies investigating associative familiarity that depend upon procedural variations of the widely used novel object recognition task. It uses an event arena in which animals are trained across numerous sessions to search for, find and dig up reward from sandwells during sample and choice trials - a prominent spatial event for a rodent. The arena could be laid out as either of two highly distinct contexts with which the animals became fully familiar throughout training. In one protocol, the location of the correct sandwell in each context remained stable across days, whereas in the other, the correct digging location varied in a counterbalanced manner across each successive session. Thus, context-specific recall of the spatial location of successful digging during choice trials was either from a stable long-term memory or could reflect context specific spatial recency of the location where reward had been available that session. Both protocols revealed effective memory recall in choice and probe tests which, at the point of test, were procedurally identical in both cases.

Abstract
Data sources Medline/PubMed, Web of Science, Scopus and Cochrane Library databases. Grey literature searches (OpenGrey, ProQuest databases), hand searches in the reference list of eligible studies and relevant journals.Study selection Randomised controlled trials (RCTs) and prospective clinical trials (PCTs) with direct comparisons between metal posts (MPs) and fibre posts (FPs). Trials contained a minimum of ten patients and endodontically treated permanent teeth that had received either single crowns or fixed partial dentures (bridges) and followed up for a minimum of one year. The primary outcome compared the difference in failure rates between FPs and MPs, with subgroup analysis comparing location (anterior/posterior), type of MP (cast post core/preformed MP) and most frequent modes of failure (debond/root fracture).Data extraction and synthesis Study selection, data collection and risk of bias assessments were completed independently by two reviewers. Disagreements were discussed with a third reviewer to reach a consensus. The risk of bias was evaluated using the Cochrane risk of bias tool (RCTs) or the ROBINS-I tool (PCTs). The quality of responses was assessed using the Grading of Recommendations Assessment, Development And Evaluation (GRADE) approach. The meta-analysis (MA) was performed using the Mantel-Haenszel method. Trial heterogeneity was assessed using random- and fixed-effects models. Inter-examiner agreement during the database search and study selection process was checked using the kappa statistic.Results After duplicates were removed, 1,026 articles were assessed and screened by title and abstract. Of these, 21 articles underwent full-text evaluation, with ten articles meeting the eligibility criteria. Eligible studies included six RCTs and four PCTs. A total of 844 endodontically treated teeth (ETT) were restored with intra-radicular posts in 704 participants. Four hundred and fifty-three ETT were restored with FPs and 391 with MPs. The mean age of participants was 42.7 (33.95-55.45) years, with a mean follow-up period of 50.95 (12-154) months. Most studies reported failures during the follow-up period, but the MA revealed no significant difference between FPs and MPs in terms of failure rates (P = 0.39; RR: 0.82 mm; CI: 0.52-1.29). Sub-analysis showed no difference in failure rates between anterior and posterior regions and no difference when comparing FPs to cast post and core vs prefabricated MPs. Root fractures and post debondings were the most common modes of failure, but within these failures, no difference was observed between FPs and MPs.Conclusions No evidence was identified for a difference in failure rates between FPs and MPs. This was independent of the type of MP and position within the arch. Reporting of RCTs and PCTs was variable and further high-quality studies are needed.

Abstract
Abstract
Objective
Identify and evaluate palliative care interventions used in peripheral vascular disease (PVD).
Background
PVD encompasses conditions with poor outcome and severe suffering, both mentally and physically, yet utilisation and research into palliative care interventions remain sparse.
Method
A systematic review of all study designs published between January 1991 and January 2020 in which people with PVD received palliative care interventions and at least one patient reported outcome was recorded.
Results
A total of eight studies involving 87037 unique patients met inclusion criteria (four cohort studies and four cross sectional studies). There were no randomised controlled studies; The small number of studies and study heterogeneity precluded meta-analysis. Only two papers recorded patient reported outcomes. Five papers found an association between palliative care and reduction in health care utilisation. Most of the studies reported that palliative care was likely underused. Only two of the studies included non-hospital patients. The methodological quality of the papers ranged from low to moderate.
Conclusions
Despite high mortality and morbidity associated with PVD, evidence of the effectiveness of palliative care in this group of patients is lacking. There are only a handful of papers on palliative care in vascular surgery and the majority are small, methodologically flawed and lack patient reported outcomes. Randomised controlled trials of palliative care interventions in patients with PVD are needed to determine optimal treatment outcomes.

Abstract
Abstract
Aim
The BOAST-12 guidelines for the management of ankle fractures aims to optimise functional recovery and reduce complications. They advise against having radiographs prior to urgent reduction of clinically deformed ankles as it could cause an unacceptable delay to subsequent management. Our study aimed to assess the effect of time to acceptable reduction on the risk of complications and time to definitive reduction.
Method
This was a retrospective observational study of patients with ankle fracture-dislocations between 2013 to 2017 at the Northern General Hospital’s Emergency Department (ED). Information collected from 2 patient groups (with and without pre-reduction radiographs), included patient demographics, time to accepted reduction, number of manipulations, operations, and subsequent complications.
Results
242 patients were identified. Time from arrival in ED to acceptable reduction was significantly longer in patients with pre-reduction radiographs versus patients without (184.5 vs 82 minutes, p < 0.00), but did not increase the overall risk of complications (p = 0.62). Pre-reduction radiographs were associated with insignificantly higher rates of post-traumatic osteoarthritis (p = 0.17) and slightly longer wait time for definitive intervention (1 vs 2 days, p = 0.72). However, this had no relationship with the number of manipulations (p = 0.53).
Conclusions
The use of pre-reduction radiographs significantly increased time to acceptable reduction of ankle fracture-dislocations. However, this was not associated with increased risk of complications or time to definitive management.

Abstract
OBJECTIVES Because few studies have been conducted on group B Streptococcus (GBS) in Nigeria, we sought to estimate GBS colonization and transmission frequencies for 500 women and their newborns and identify risk factors for both outcomes. METHODS GBS strains were characterized for antibiotic susceptibilities, capsule (cps) genotype, pilus island profile and multilocus sequence type (ST). RESULTS In all, 171 (34.2%) mothers and 95 (19.0%) of their newborns were colonized with GBS; the vertical transmission rate was 48.5%. One newborn developed early-onset disease, yielding an incidence of 2.0 cases per 1000 live births (95% CI 0.50-7.30). Rectal maternal colonization (OR 26.6; 95% CI 13.69-51.58) and prolonged rupture of membranes (OR 4.2; 95% CI 1.03-17.17) were associated with neonatal colonization, whereas prolonged membrane rupture (OR 3.4; 95% CI 1.04-11.39) and young maternal age (OR 2.0; 95% CI 1.22-3.39) were associated with maternal colonization. Women reporting four or more intrapartum vaginal examinations (OR 6.1; 95% CI 3.41-10.93) and douching (OR 3.7; 95% CI 2.26-6.11) were also more likely to be colonized. Twelve STs were identified among 35 mother-baby pairs with evidence of transmission; strains of cpsV ST-19 (n = 9; 25.7%) and cpsIII ST-182 (n = 7; 20.0%) predominated. CONCLUSIONS These data demonstrate high rates of colonization and transmission in a population that does not use antibiotics to prevent neonatal infections, a strategy that should be considered in the future.

Abstract
Facial expression of emotion is crucial to social interaction and emotion regulation; therefore, altered facial expressivity can be a contributing factor in social isolation, difficulties with emotion regulation and a target for therapy. This article provides a systematic review and meta-analysis of the literature on automatic emotional facial expression in people with non-psychotic disorders compared to healthy comparison groups. Studies in the review used an emotionally salient visual induction method, and reported on automatic facial expression in response to congruent stimuli. A total of 39 studies show alterations in emotional facial expression across all included disorders, except anxiety disorders. In depression, decreases in facial expression are mainly evident for positive affect. In eating disorders, a meta-analysis showed decreased facial expressivity in response to positive and negative stimuli. Studies in autism partially support generally decreased facial expressivity in this group. The data included in this review point towards decreased facial emotional expressivity in individuals with different non-psychotic disorders. This is the first review to synthesise facial expression studies across clinical disorders.

Abstract
Abstract
A comprehensive whole genome analysis of a large breast cancer cohort of 560 cases (Nik-Zainal et al, submitted 2015) reports novel and existing DNA substitution and rearrangement signatures next a comprehensive list of events driving the breast cancer cell to its malignant potency. In the current study, we linked the observed genetic diversity to the breast cancer transcriptome for 260 cases for which whole genome and whole transcriptome data were both available.
Cluster analysis of the global gene expression showed the familiar view of a coherent basal-like and a heterogeneous luminal subgroup. New and previously reported1 subtype-specific aberrations with concordant expression changes were found in TP53, PIK3CA, PTEN, CCND1, CDH1 and GATA3, and mutations in PIK3CA, PTEN, AKT1 and AKT2 were mutually exclusive confirming they are active in the same pathway in breast cancer.
Integrating the identified DNA substitutions signatures with the transcriptome, we observed that the total number of substitutions in a cancer, irrespective of substitution type, was positively associated with cell cycle regulated gene expression and with adverse outcome.
In addition and more remarkably, we observed that the number substitution of two substitution signatures2 particularly associated with immune-response specific gene expression, with increased amount of tumor infiltrating lymphocytes and with a better outcome. These two signatures comprised 1) mutations of the APOBEC-type (predominant C>G in a TCN context), and 2) mutations which lacks specific features but which are strongly associated with genetic and epigenetic inactivating aberrations in BRCA1 and BRCA2.
Thus, while earlier reports3-5 imply that the sheer number of driver events triggers an immune-response, we refine this statement by observing that substitutions of a particular type are much very effective in doing so explaining the superior outcome of cancer having these particular types of substitutions. This result also implies that purposefully augmenting T-cell reactivity against amino-acid substitutions resulting from either of these two DNA substitution types could potentially improve immunotherapies in breast cancer.

Abstract
In this study, the development of a mechanostatistical model of three-dimensional cortical bone remodelling informed with in vivo equine data is presented. The equine model was chosen as it is highly translational to the human condition due to similar Haversian systems, availability of in vivo bone strain and biomarker data, and furthermore, equine models are recommended by the US Federal Drugs Administration for comparative joint research. The model was derived from micro-computed tomography imaged specimens taken from the equine third metacarpal bone, and the Frost-based 'mechanostat' was informed from both in vivo strain gauges and biomarkers to estimate bone growth rates. The model also described the well-known 'cutting cone' phenomena where Haversian canals tunnel and replace bone. In order to make this model useful in practice, a partial least squares regression (PLSR) surrogate model was derived based on training data from finite element simulations with different loads. The PLSR model was able to predict microstructure and homogenised Young's modulus with errors less than 2.2% and 0.6%, respectively.

Abstract
Little is known about the experiences of patients with severe comorbidity discharged from Intensive Care Units (ICUs). This project aimed to determine the effects of an ICU stay for patients with severe comorbidity by comparing 1) quality of life (QOL), 2) the symptom profile of hospital survivors and 3) health service use after hospital discharge for patients admitted to ICU with and without severe comorbidity. A case-control study was used. Patients with severe comorbidity were matched to a contemporaneous cohort of ICU patients by age and severity of illness. Assessment tools were the Medical Outcome Study 36-item short-form and European Organisation for Research and Treatment of Cancer QLQ-C15-PAL questionnaires for QOL and the Symptom Assessment Scale for symptom distress. A proportional odds assumption was performed using an ordinal regression model. The difference in QOL outcome was the dependent variable for each pair. Health service use after discharge from ICU was monitored with patient diaries. Patients aged 18+ years admitted to an ICU in a metropolitan teaching hospital between 2011 and 2012 were included. We recruited 30 cases and 30 controls. QOL improved over the six months after hospital discharge for patients with and without severe comorbidity ( P <0.01) within the groups but there was no difference found between the groups ( P >0.3). There was no difference in symptoms or health service use between patients with and without severe comorbidity. ICU admission for people with severe comorbidity can be appropriate to stabilise the patient's condition and is likely to be followed by some overall improvement over the six months after hospital discharge.

Abstract
UNLABELLED Appendicitis is a common clinical diagnosis aided by biochemical, haematological and radiological investigations. The role of some investigations, such as bilirubin, is controversial but could indicate complicated appendicitis. Accurate diagnosis enables prioritisation of patients on operating lists and a possible reduction in unnecessary investigations. METHODS This is a retrospective cohort study of 1347 patients who underwent appendicectomy. Statistical analysis of serum bilirubin levels was performed according to histological classification of appendicitis. RESULTS Mean serum bilirubin levels; perforated/gangrenous appendicitis 20.5 mg/L (SD 12.6), inflamed appendicitis mean 17.5 mg/L (SD CI 11.1), normal appendix mean 12.6 mg/L (7.0). Kruskal-Wallis indicated bilirubin levels were significantly different (H=128.87, df=4, p<.001) between histological groups, and a post hoc analysis with Bonferroni adjustment showed perforated/gangrenous to be significantly higher than all other groups (p<.001). Binary logistic regression combining White Cell Count (WCC) level, C-Reactive Protein (CRP) and Bilirubin levels gave a sensitivity and specificity of .69 with AUROC=.766 (std error .015) for gangrenous/perforated. Assessment according to clinical relevance showed only 30.4% of patients with an abnormally raised bilirubin had gangrenous/perforated appendicitis. CONCLUSIONS Serum bilirubin does not independently predict perforation/gangrenous appendicitis. Statistical analysis showed differences in mean bilirubin between histological groups however this did not relate to clinical significance as bilirubin levels were still within normal clinical limits. Diagnosis of complicated appendicitis should be made on clinical grounds, with utilization of biochemical/haematological investigations, but there should not be independent reliance on investigations such as bilirubin.

Abstract
Routine DXA scanning in a 68-year-old asymptomatic man undergoing long-term bisphosphonate treatment for osteogenesis imperfecta showed unexplained loss of bone mineral density in two lumbar vertebrae. Subsequent radiographs revealed a 14-cm abdominal aortic aneurysm eroding the vertebrae. The importance of reviewing all the vertebrae in DXA scans is emphasized, and reasons for the absence of symptoms suggested.

Abstract
BACKGROUND. The Modified Early Warning Score (MEWS) is used to monitor medical inpatients in hospitals in the developed world. The South African Triage Score (SATS) was developed from the MEWS, and its use throughout South Africa has been proposed. OBJECTIVES. We aimed to assess the effectiveness of the SATS in an emergency department (ED) in a rural setting in KwaZulu-Natal (KZN). METHODS. A prospective cross-sectional study undertaken over a 1-month period in June 2009 of patients in the ED of a government hospital in rural KZN, the referral centre for 22 peripheral hospitals. Data capture included physiological parameters, mobility and trauma scores, a list of selected clinical conditions (physician discriminator list), MEWS and SATS scores, final clinical diagnosis, and outcome in the ED (death, hospital admission or discharge). Outcome measures were under- and over-triage rates according to both systems. RESULTS. Over the study period, 589 patients were triaged and their data analysed. The MEWS under-triaged 15.1% (over-triaged 8.3%) of cases that needed admission, compared with an under-triage rate of 4.4% (over-triage rate 4.3%) when the SATS was used. CONCLUSION. Our study supports use of the SATS as a primary triage score in South African urban and rural hospitals. The SATS is superior to the MEWS as a triage scoring system in a rural hospital ED in KZN, its rates of under- and over-triage falling within the limits of the American College of Surgeons Committee on Trauma (ACSCOT) guidelines.

Abstract
This brief report discusses the introduction of routine Glutamic Acid Decarboxylase Antibody (GADA) testing in primary care for newly diagnosed diabetes. GADA testing is well used and the majority of people found to be positive are initiated on insulin rapidly and progress to require a basal bolus regime.
