Abstract
Abstract
Aim
To investigate whether implant design affect (1)incidence of anterior knee pain, (2)patient reported outcomes and (3)reintervention rates in a resurfaced vs non-resurfaced Total Knee Arthroplasty (TKA).
Method
MEDline, pubmed and google scholar studies were evaluated using SIGN assessment tool and data analysis was conducted using Review Manager 5.2 on only randomised controlled trials. Search terms: arthroplasty, replacement, knee (Mesh), TKA, prosthesis, patella, patellar resurfacing, patellar retaining.
Results
33 randomised controlled studies were identified. A total of 11 used the modern “patella-friendly” implants and 22 used the older “patella non-friendly” implants.
There was no significant difference in anterior knee pain rates for either surgical option. When using patella-friendly implant, patella resurfacing results in a statistically higher clinical (P 0.007, MD -0.77) and functional (P < 0.0001, MD -1.87) KSS than the non-resurfaced counterparts, but scores were not clinically significant. When the patella was not resurfaced, there was a significant increased risk of reoperation with “non-patella friendly” implant (p=0.04, OR 1.42, CI 1.01, 2.00), whilst there was no significant difference between reoperation rates for the “patella friendly” implants (OR 1.17, CI 0.59,2.30).
Conclusions
Patella implant design has been shown to significantly improve KSS scores but with no clinical significance. Risk of further procedures was significantly higher in non-resurfaced patella TKAs with “non-friendly” implants, likely due to increased rates of anterior knee pain in these older generation implants leading to secondary resurfacing. However, when utilising “patella-friendly” implants, resurfacing does not lower reintervention rates. This meta-analysis finds no clinical indication to resurface the patellar whilst performing a TKA.

Abstract
Recent advances in citizen weather station (CWS) networks, with data accessible via crowd-sourcing, provide relevant climatic information to urban scientists and decision makers. In particular, CWS can provide long-term measurements of urban heat and valuable information on spatio-temporal heterogeneity related to horizontal heat advection. In this study, we make the first compilation of a quasi-climatologic dataset covering six years (2015-2020) of hourly near-surface air temperature measurements obtained via 1560 suitable CWS in a domain covering south-east England and Greater London. We investigated the spatio-temporal distribution of urban heat and the influences of local environments on climate, captured by CWS through the scope of Local Climate Zones (LCZ)-a land-use land-cover classification specifically designed for urban climate studies. We further calculate, for the first time, the amount of advected heat captured by CWS located in Greater London and the wider south east England region. We find that London is on average warmer by about 1.0 ∘C-1.5 ∘C than the rest of south-east England. Characteristics of the southern coastal climate are also captured in the analysis. We find that on average, urban heat advection (UHA) contributes to 0.22 ± 0.96 ∘C of the total urban heat in Greater London. Certain areas, mostly in the centre of London are deprived of urban heat through advection since heat is transferred more to downwind suburban areas. UHA can positively contribute to urban heat by up to 1.57 ∘C, on average and negatively by down to -1.21 ∘C. Our results also show an important degree of inter- and intra-LCZ variability in UHA, calling for more research in the future. Nevertheless, we already find that UHA can impact green areas and reduce their cooling benefit. Such outcomes show the added value of CWS when considering future urban design.

Abstract
Abstract
Introduction
Anterior Cruciate Ligament(ACL) rupture is a common sporting injury. Return to sport is a key objective for patients.
The aim of this study was to investigate return to pre-injury level sport at 12- and 24-months post reconstruction and to relate this to types of sport and to patient satisfaction.
Method
A questionnaire was developed, piloted, and then completed by 77 patients that had undergone ACL reconstruction between 2013-2016.
Results
30% of patients returned to pre-injury level of sport at 12 months and 43% by 24 months’ post ACL reconstruction. There was a significant(P = 0.037) relationship between the type of sports that participants played prior to injury and the return to pre-injury level. Sports that involved jumping, hard pivoting and cutting were associated with a lower rate of return to sport. General health profile of the patients was found to be significantly higher in patients that returned to sport(P = 0.024). There was a significant association with return to sport and higher satisfaction and healthcare experience score(P = 0.001).
Conclusions
Patient satisfaction correlated with return to sport. This was inversely related to sports involving jumping, hard pivoting and cutting. Which further illustrates how patient satisfaction post ACL reconstruction was linked to type of sport.

Abstract
Abstract
Background
The risk of typical atrial flutter (AFL) is increased by factors that increase right atrial (RA) size or cause scarring to reduce conduction velocity. These characteristics ensure the macro re-entrant wave front does not meet its refractory tail. The time taken to traverse the circuit would take account of both of these characteristics (being equal to distance divided by velocity), and may provide a superior marker of propensity to develop AFL.
Purpose
To investigate right atrial collision time (RACT) as a marker of typical AFL.
Methods
This single centre, prospective study recruited consecutive typical AFL ablation cases that were in sinus rhythm. Controls were consecutive cases other than atrial fibrillation and >50 years of age. Exclusion criteria for both groups were a prior ablation in the RA and class I and III antiarrhythmics. While pacing the coronary sinus ostium at 600 ms, a local activation time map was created to locate the latest collision point on the anterolateral wall, excluding the RA appendage (Figure 1). This RACT approximates half a revolution.
Results
The AFL group's (n=34) mean RACT was 132.5±15.06 vs 98.7±12.23ms in the controls (n=40) (p<0.01). No significant difference was observed for age (mean 65.6 vs 62.6 (p=0.18)), male (68.8% vs 60% (p=0.59)), body surface area (mean 2.1 vs 2.03 m2 (p=0.24)). The RACT also proved to be a superior marker than the echocardiographic measurement of right atrial area in an apical four chamber view (mean 17.8 vs 16.3 cm2 (p=0.21).A ROC curve indicated an AUC of 0.97 (95% CI: 0.93–1.0, p<0.01). A RACT cut-off of 120 ms had a specificity of 99% and a sensitivity of 75%.
Conclusion
RACT is a novel and promising marker of propensity for typical AFL. The ability to predict AFL would be of significant clinical value given the risk of stroke and frequent need for ablation.

Abstract
Resuscitative endovascular balloon occlusion of the aorta (REBOA) is used to augment resuscitation in patients with noncompressible torso hemorrhage, which is a leading cause of death on the battlefield. However, the implementation of REBOA has resulted in considerable debate within the military medical community. We present a case of the first successful placement of an REBOA by a small surgical team within a mobile rotary wing platform.

Abstract
OBJECTIVES Bowel cancer screening home-testing kits are offered every two years to individuals aged 60-74 years in the United Kingdom (UK), with prisoners eligible for screening in the same way as the general population. There are currently major changes planned to the bowel cancer screening programme in England, with the transition to the single-sample faecal immunochemical test (FIT) and the planned lowering of the age limit from 60 to 50 years. In this project, we aimed to explore processes and beliefs around bowel cancer screening in an English prison. STUDY DESIGN This is a qualitative study. METHODS Semistructured qualitative interviews were conducted with eight prisoners and four staff members in a male prison in North West England. Data were analysed via thematic analysis. RESULTS Promoting and impeding factors to screening were identified. There was high willingness amongst prisoners to be screened for bowel cancer, with screening seen as important and having benefits for the individual and healthcare system. However, there was often low awareness of screening and there were psychological challenges associated with screening. Prison healthcare staff were widely respected and were a motivator to accept screening, with prisoners viewing prison as a good opportunity to access health care. Despite this, prison life was characterised by competing priorities, with security taking precedence, and screening sometimes a low priority for staff and prisoners. There were also considerable logistical challenges to delivering bowel cancer screening in a prison, and the system was not comparable with that in the community. Providing good-quality understandable information, though challenging, was key. CONCLUSIONS This is the first project to explore entering the bowel cancer screening programme in UK prisons, and promoting and impeding factors to the take-up of screening have been identified. This information could be practically used by local commissioners and policymakers to aid the design of staff and prisoner interventions to maximise uptake of bowel cancer screening in prisons. As the planned changes to bowel cancer screening in England are likely to increase the number of eligible prisoners, this work could also be used to inform any service reconfiguration required to accommodate these changes.

Abstract
Abstract
Background
Risk stratification following an acute coronary syndrome (ACS) is of utmost importance, in order to identify patients at higher risk of subsequent cardiovascular events. Diabetic patients have a significantly worse prognosis, so new risk prediction tools are important to better identify and risk stratify high risk patients within this important ACS subpopulation.
Aim
The aim of this study was to identify the best predictors of a new ACS, in a single-center database of ACS, resorting to machine learning and artificial intelligence, and to compare the Global Registry of Acute Coronary Events (GRACE) risk score's relevance for risk discrimination in a general ACS population versus a subpopulation of diabetic patients.
Methods
In a single center, 5977 patients admitted due to ACS between 2004 and 2017 and alive at discharge were studied. In the subpopulation of diabetic patients (n=3429), each covariate present in the database was analyzed separately with a Cox proportional hazard model with three terms – subpopulation belonging indicator, covariate, interaction term. The p-value of the interaction term was used to rank variables. The more significant the interaction term, the stronger the change in relationship between patients in the subpopulation and the risk of a new ACS, compared to the one in the general population.
Results
During long term follow-up, 13% of patients (n=771) experienced a second event. Kaplan-Meier curve represents how ACS free-survival depends on the GRACE risk score and group of interest. In the general population and in the subpopulation of diabetic patients, the GRACE score was used to further divide patients into 3 terciles, of which only the lower and upper tercile are shown (GRACE ≤113 and GRACE >144, respectively). The solid lines represent Kaplan-Meier curves for diabetic patients, and the dotted lines in the general population. Pink or grey colour of the curves represent the stratification level of the covariate.
Conclusions
In our model, the GRACE risk score was found to be a better discriminator of risk of futher ACS in diabetic patients than in the general ACS population. Strikingly, a higher GRACE score predicts a lower rate of readmission, probably because many patients will die in the index hospitalization or out of hospital. This finding reinforces the usefulness of the GRACE score in high risk patients and may improve risk stratisfication in diabetic post-ACS patients, making sure that they are closely followed and submitted to optimal risk factor management, in order to improve their post-ACS prognosis.

Abstract
INTRODUCTION Aberrant function of granulosa cells has been implicated in the pathophysiology of PCOS. MATERIALS & METHODS Granulosa lutein (GL) cells were collected during oocyte retrieval for IVF/ICSI. RT-qPCR was used to compare gene expression between 12 control women, 12 with ovulatory PCO and 12 with anovulatory PCOS. To examine which genes are directly regulated by androgens, GL cells from an additional 12 control women were treated in-vitro with 10 nM dihydrotestosterone (DHT). RESULTS GL cells from women with PCOS showed reduced expression of CYP11A1 3-fold (p = 0.005), HSD17B1 1.8-fold (p = 0.02) and increased expression of SULT1E1 7-fold (p = 0.0003). Similar results were seen in ovulatory women with PCO. GL cells treated with 10 nM DHT showed a 4-fold (p = 0.03) increase in expression of SULT1E1 and a 5-fold reduction in SRD5A1 (p = 0.03). CONCLUSIONS These findings support the notion that aberrant regulation of steroid metabolism or action play a part in ovarian dysfunction in PCOS.

Abstract
Postoperative management of malignant hyperthermia (MH) susceptible patients has changed substantially over the last 20 years, with many patients now managed as day cases. Our previous policy was to monitor known MH susceptible patients (and relatives of known MH susceptible individuals not yet investigated by muscle biopsy) for four hours in the Post Anaesthetic Care Unit. However, anaesthetic literature reports suggest that MH reactions usually commence within one hour of anaesthesia. For this reason we conducted a retrospective review of Post Anaesthetic Care Unit data in 254 MH susceptible/related patients treated between 1991 and late 2000. On the basis of this review we instituted a policy change and reduced our monitoring time to one hour in the Post Anaesthetic Care Unit with a further 1.5h in a step-down unit if indicated. A prospective study in a further 68 MH susceptible/related patients showed that no MH reactions were missed due to the shorter monitoring period.

Abstract
A search for boosted dark matter using 161.9 kt yr of Super-Kamiokande IV data is presented. We search for an excess of elastically scattered electrons above the atmospheric neutrino background, with a visible energy between 100 MeV and 1 TeV, pointing back to the Galactic center or the Sun. No such excess is observed. Limits on boosted dark matter event rates in multiple angular cones around the Galactic center and Sun are calculated. Limits are also calculated for a baseline model of boosted dark matter produced from cold dark matter annihilation or decay. This is the first experimental search for boosted dark matter from the Galactic center or the Sun interacting in a terrestrial detector.

Abstract
OBJECTIVE Three dimensional (3D) surface imaging is a viable alternative to traditional body morphology measures, but the feasibility of using this technique with people with obesity has not been fully established. Therefore, the aim of this study was to investigate the validity, repeatability and acceptability of a consumer depth camera 3D surface imaging system in imaging people with obesity. METHODS The concurrent validity of the depth camera based system was investigated by comparing measures of mid-trunk volume to a gold-standard. The repeatability and acceptability of the depth camera system was assessed in people with obesity at a clinic. RESULTS There was evidence of a fixed systematic difference between the depth camera system and the gold standard but excellent correlation between volume estimates (r2=0.997), with little evidence of proportional bias. The depth camera system was highly repeatable - low typical error (0.192L), high intraclass correlation coefficient (>0.999) and low technical error of measurement (0.64%). Depth camera based 3D surface imaging was also acceptable to people with obesity. CONCLUSION It is feasible (valid, repeatable and acceptable) to use a low cost, flexible 3D surface imaging system to monitor the body size and shape of people with obesity in a clinical setting.

Abstract
BACKGROUND Current algorithms and device morphology templates have been proposed in current Implantable Cardioverter-Defibrillators (ICDs) to minimize inappropriate therapies (ITS), but this has not been completely successful. AIM Assess the impact of a deliberate strategy of using an atrial lead implant with standardized parameters; based on all current ICD discriminators and technologies, on the burden of ITS. METHOD A retrospective single-centre analysis of 250 patients with either dual chamber (DR) ICDs or biventricular ICDs (CRTDs) over a (41.9 ± 27.3) month period was performed. The incidence of ITS on all ICD and CRTD patients was chronicled after the implementation of standardized programming. RESULTS 39 events of anti-tachycardial pacing (ATP) and/or shocks were identified in 20 patients (8% incidence rate among patients). The total number of individual therapies was 120, of which 34% were inappropriate ATP, and 36% were inappropriate shocks. 11 patients of the 250 patients received ITS (4.4%). Of the 20 patients, four had ICDs for primary prevention and 16 for a secondary prevention. All the episodes in the primary indication group were inappropriate, while seven patients (43%) of the secondary indication group experienced inappropriate therapies. CONCLUSIONS The burden of ITS in the population of patients receiving ICDs was 4.4% in the presence of atrial leads. The proposed rationalized programming criteria seems an effective strategy to minimize the burden of inappropriate therapies and will require further validation.

Abstract
Introduction Uncontrolled haemorrhage is the leading cause of death on the battlefield, and two-thirds of these deaths result from non-compressible haemorrhage. Blood salvage and autotransfusion represent an alternative to conventional blood transfusion techniques for austere environments, potentially providing blood to the casualty at point of injury. The aim of this paper is to describe the design, development and initial proof-of-concept testing of a portable blood salvage and autotransfusion technology to enhance survivability of personnel requiring major medical interventions in austere or military environments. Method A manually operable, dual-headed pump was developed that removes blood from site of injury to a collection reservoir (upper pump) and back to casualty (lower pump). Theoretical flow rate calculations determined pump configuration and a three-dimensionally printed peristaltic pump was manufactured. Flow rates were tested with fresh bovine blood under laboratory conditions representative of the predicted clinical environment. Results Mathematical modelling suggested flow rates of 3.6 L/min and 0.57 L/min for upper and lower pumps. Using fresh bovine blood, flow rates produced were 2.67 L/min and 0.43 L/min. To mimic expected battlefield conditions, upper suction pump flow rate was calculated using a blood/air mixture. Conclusion The authors believe that this technology can potentially enhance survivability for casualties in austere and deployed military settings through autotransfusion and cell concentration. It reduces negative effects of blood donation on the conventional donor pool, and potentially negates the logistical constraints associated with allogenic transfusions.

Abstract
UNLABELLED LRP5 loss-of-function mutations have been shown to cause profound osteoporosis and have been associated with impaired insulin sensitivity and dysregulated lipid metabolism. We hypothesized that gain-of-function mutations in LRP5 would also affect these parameters. We therefore studied individuals with LRP5 gain-of-function mutations exhibiting high bone mass (HBM) phenotypes and found that while there was no detected change in insulin sensitivity, there was a significant reduction in serum LDL. INTRODUCTION Wnt signaling through LRP5 represents a newly appreciated metabolic pathway, which potentially represents a target for drug discovery in type 2 diabetes and hyperlipidemia. Studies in animal models suggest a physiologic link between LRP5 and glucose and lipid homeostasis; however, whether it plays a similar role in humans is unclear. As current literature links loss-of-function LRP5 to impaired glucose and lipid metabolism, we hypothesized that individuals with an HBM-causing mutation in LRP5 would exhibit improved glucose and lipid homeostasis. Since studies in animal models have suggested that Wnt signaling augments insulin secretion, we also examined the effect of Wnt signaling on glucose-stimulated insulin secretion on human pancreatic islets. METHODS This was a matched case-control study. We used several methods to assess glucose and lipid metabolism in 11 individuals with HBM-causing mutations in LRP5. Affected study participants were recruited from previously identified kindreds with HBM-causing LRP5 mutations and included 9 males and 2 females. Two subjects that were being treated with insulin for type 2 diabetes were excluded from our analysis, as this would have obscured our ability to determine the impact of gain-of-function LRP5 mutations on glucose metabolism. The mean age of the evaluated study subjects was 55 ± 7 with a mean BMI of 27.2 ± 2.0. Control subjects were matched and recruited from the general community at an equivalent ratio, with 18 males and 4 females (mean age 56 ± 4; mean BMI 27.2 ± 1.0). Study testing was conducted at an academic medical center. RESULTS There were no statistically significant differences between affected and matched control populations for HbA1c (p = 0.06), eAG (p = 0.06), insulin (p = 0.82), HOMA-B (p = 0.34), or HOMA-IR (p = 0.66). The mean Insulin Sensitivity Index (ISI) was also similar between control and affected individuals. Total cholesterol (p = 0.43), triglycerides (TG) (p = 0.56), and HDL (p = 0.32) were not different between the same two groups. In a small subset of studied subjects, intramyocellular and hepatic lipid content were similar in the affected individuals and controls when quantified by proton magnetic resonance spectroscopy (MRS). However, the mean value for serum LDL was significantly lower (p = 0.04) in affected individuals. In primary human islets, there were no differences between control and Wnt treatment groups for insulin secretion measured as area under the curve (AUC) for first phase (p = 0.17) or second phase (p = 0.33) insulin secretion. CONCLUSIONS Although our sample size was small, our data do not support the hypothesis that HBM-causing LRP5 mutations, associated with increased Wnt signaling, improve glucose metabolism in humans. However, it does appear that LRP5 variants may affect LDL metabolism, a major risk factor for coronary artery disease. The molecular mechanisms underpinning this effect warrant further study.

Abstract
BACKGROUND: Pregnancy is associated with changes in body shape that influence body image satisfaction. Body dissatisfaction during pregnancy is a concern because of the potential association with negative behaviours, such as unhealthy dieting, which have been linked to poor pregnancy and neonatal outcomes. This is of particular concern for pregnant youth as they are already at increased risk for medical complications. Body image dissatisfaction in pregnancy is also an important determinant of depressive symptoms in pregnancy and postpartum. Given that pregnant and parenting youth (PPY) have poorer mental health outcomes, including a high rate of both antenatal and postpartum depression, examining the relationship between body image and depression during pregnancy is particularly important.
OBJECTIVES: The objectives of this study were to 1) examine psychological profiles of PPY regarding body image and related issues, 2) explore differences between younger and older PPY, and 3) compare psychological profiles of those who are pregnant versus not pregnant.
DESIGN/METHODS: Data was collected from 75 PPY from 2 urban social service agencies via electronic questionnaires. Demographic data and scores from several validated self-report measures related to self-esteem, body esteem, eating disorder behaviours and depression were collected. Research ethics board approval was obtained prior to the onset of the study.
RESULTS: Youth participants had a mean age of 19.6 years (SD=2.68); 29.3% (n=22) were pregnant at the time of the survey and 82.7 % (n=62) had at least 1 child. Youth reported a past history of depression (76.9%), anxiety (70.5%), drug/alcohol abuse (46.2%), and eating disorder (28.2%). Descriptive analyses revealed that PPY reported depression scores that were in the borderline clinical range (Edinburgh postnatal depression scale: mean 11.57, SD 6.26), whereas they scored within the relative normal range for all other psychological measures. There were no significant differences in any of the survey scores when comparing younger to (n=39, mean age 17.5 yrs) older participants (n=36, mean age 22 yrs); although when comparing pregnant (n=22) participants and non-pregnant (n=53) participants significant differences were found among scores of body esteem (t=-2.173, p=0.034) and eating disorder behaviours (t=2.713, p=0.008).
CONCLUSION: This study adds to the very limited research regarding adolescents' experience with body image during motherhood and the postpartum years, and can inform future program development for pregnant teens and young mothers struggling with poor body image. Future research is needed to continue exploring how adolescent body image during pregnancy and postpartum may differ and how this affects maternal and child outcomes.

Abstract
BACKGROUND/OBJECTIVES Participants are often asked to replicate their diet before each trial to control dietary intake. However, little is known about the reproducibility of the diet using different approaches. The aim was to assess the reproducibility of a diet when a controlled diet (Cdiet), food record (Frecord) and 24-h dietary recall (Drecall) were used as dietary standardisation techniques. SUBJECTS/METHODS Thirty athletes completed six visits to the laboratory. On the first occasion, a Drecall was performed and subjects were asked to replicate exactly the same diet on the day before visit 2, when another Drecall was performed. The day before the third visit, subjects completed a Frecord, which was presented at visit 3 and assessed using Drecall to ensure comparability between methods. Subjects were asked to replicate this Frecord before visit 4, which was assessed using Drecall. Finally, subjects were provided with a Cdiet of known composition, which they consumed for 24 h before visits 5 and 6. For each method, the difference in energy and macronutrient intakes between both occasions was measured. RESULTS Despite finding no differences in mean energy and macronutrient intakes between visits for any technique, important within-subject differences were apparent. The range of percentage coefficient of variation for all variables was between 2.7 and 5.8% for Cdiet, 10.1 and 18.6% for Frecord and 7.1 and 11.7% for Drecall. CONCLUSIONS This study has shown that Cdiet is the best approach to standardise dietary intake, especially when the expected effect of an intervention is small and an enhanced reliability is required.

Abstract
BACKGROUND Medical illnesses are associated with a modest increase in crash risk, although many individuals with acute or chronic conditions may remain safe to drive, or pose only temporary risks. Despite the extensive use of national guidelines about driving with medical illness, the quality of these guidelines has not been formally appraised. AIM To systematically evaluate the quality of selected national guidelines about driving with medical illness. DESIGN A literature search of bibliographic databases and Internet resources was conducted to identify the guidelines, each of which was formally appraised. METHODS Eighteen physicians or researchers from Canada, Australia, Ireland, USA and UK appraised nine national guidelines, applying the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument. RESULTS Relative strengths were found in AGREE II scores for the domains of scope and purpose, stakeholder involvement and clarity of presentation. However, all guidelines were given low ratings on rigour of development, applicability and documentation of editorial independence. Overall quality ratings ranged from 2.25 to 5.00 out of 7.00, with modifications recommended for 7 of the guidelines. Intra-class coefficients demonstrated fair to excellent appraiser agreement (0.57-0.79). CONCLUSIONS This study represents the first systematic evaluation of national-level guidelines for determining medical fitness to drive. There is substantive variability in the quality of these guidelines, and rigour of development was a relative weakness. There is a need for rigorous, empirically derived guidance for physicians and licensing authorities when assessing driving in the medically ill.

Abstract
PURPOSE Diabetes has long been known to have an impact on bone repair. More recently, however, most diabetic patients receive medications to normalise this hyperglycaemic environment. To date, no studies have investigated the effects of diabetic medications on fracture healing in humans. METHOD Patients were identified from two tertiary trauma centres. Inclusion criteria were adult patients having sustained a closed diaphyseal femoral or tibial fracture, treated surgically. Exclusion criteria were open, pathological or peri-prosthetic fractures, and patients having sustained polytrauma. Matched non-diabetic controls were identified, matched for age, sex, fracture classification and osteosynthesis. Output measures were: time to callus first appearance, bridging of involved cortices and time to union, along with the eventual outcome: union/non-union. RESULTS A total of 36 (25 males) eligible patients were identified with a control group of 166 patients (138 males). ANOVA demonstrated class of medication to have a significant effect at two of the three time points and on the eventual outcome. Multiple regression analysis also demonstrated significant impact (p = 0.02). CONCLUSION All classes of medication demonstrated anti-osteogenic effects compared to the control cohort. Biguanides demonstrated this in contrast to the in vitro evidence to date. Sulphonylureas demonstrated this to a greater extent; however, no in vitro evidence is available for comparison within this class. Clinicians should be aware of these delays in bone healing when treating diabetic patients and aim for optimal blood glucose control until such time as further research can be undertaken.

Abstract
The aim of this exploratory pilot study was to adapt a psychological intervention to improve adherence to medication for patients with rheumatoid arthritis (RA). The approach draws on cognitive behavioural therapy (CBT) techniques, including motivational interviewing . The current study aimed to (i) adapt the intervention for patients with RA, (ii) assess its effectiveness in improving adherence to medication and (iii) evaluate patients' experience of the intervention. Participants were randomly allocated to either the 'intervention group' (N = 10), receiving up to six weekly sessions of 'Compliance Therapy', or to the 'wait-list control' group (N = 8), who received standard care. Data was collected pre intervention (baseline), post intervention and at six weeks post intervention (follow-up). Eighteen female participants with a mean age of 48.78 years (SD 15.12) took part in the study. Comparisons across the two time points for each group found that only those in the 'intervention' group demonstrated significant improvement in mean scores on adherence measures. Between-group comparisons were not significant. The pilot study suggests that an intervention based on CBT may improve adherence in patients with RA, but further research is required.
