Abstract
PURPOSE/OBJECTIVE(S) Paragangliomas of the head and neck (HN) are benign, slow-growing neoplasms that are rarely functional. Treatment is often indicated for patients presenting with mass effect, cranial neuropathies, or pulsatile tinnitus. Radiotherapy, traditionally conventionally fractionated, is often used for primary, post-operative, and salvage therapy, given its excellent control rates and reduced risks to adjacent neurovascular structures. Stereotactic ablative radiation (SAbR) offers shorter treatment time, and modern techniques eliminate margins to improve organ-at-risk avoidance. SAbR may offer additional radiobiological sparing of normal structures over single-fraction SAbR. We aimed to evaluate tumor and symptom response, acute and late toxicity rates, and recurrence patterns in HN paraganglioma patients treated with 25 Gy in 5 fractions. MATERIALS/METHODS Retrospective chart review collected baseline patient and tumor information, treatment and dosimetry details, acute and long-term toxicity grades (per the CTCAE v. 5.0), symptom and tumor response, and survival. Local control was defined as the absence of local enlargement (per RECIST v. 1.1) or marginal failure and was estimated using the Kaplan-Meier method. RESULTS Between December 2009-March 2020, 39 patients received 25 Gy in 5 fractions to 43 HN paragangliomas, of which 17 were treated in 11 patients with hereditary paraganglioma-pheochromocytoma syndrome. Fifteen targets were post-operative recurrent or residual tumors. There were 27 jugulotympanic tumors, 4 jugular, 1 tympanic, 8 vagal, 5 carotid body, and 2 jugulotympanic or vagal. Median follow-up time was 3.3 years (range 0-11.4 years), and 21 targets had at least 4 years of follow-up. Tumor volume decreased by a median of 37%. Three-year local control was 100%. One patient, known to harbor an SDHD mutation, had 2 out-of-field recurrences within the post-operative bed at 7.1 years. Two patients experienced 2 marginal recurrences within the post-operative bed at 6.1 and 8.4 years: one had an SDHB mutation and developed metastatic disease, and the other did not have genetic testing. The most common grade 1-2 acute toxicities were headache and fatigue; the most common grade 1-2 late toxicities were dysphagia and otalgia. There were no grade >2 acute toxicities. A late grade 3 aspiration event was seen in 1 patient who presented with paralyzed vocal cord requiring multiple medialization laryngoplasties. Within 6 months of SAbR, 18% of symptoms or toxicities improved or resolved; 34% improved or resolved more than 6 months after SAbR. CONCLUSION This is the largest series of HN paragangliomas treated with SAbR, detailing a 10-year experience with a 5-fraction regimen that is well-tolerated and achieves excellent local control. Post-SAbR recurrences occurred outside of the radiation field but within the post-operative bed, suggesting that some post-operative patients may benefit from expanded radiation volumes or close surveillance for salvage therapy.

Long-term outcomes of SBRT for PSMA PET detected oligometastatic prostate cancer. Radiat Oncol 2023; 18:127. [PMID: 37528487 PMCID: PMC10394924 DOI: 10.1186/s13014-023-02302-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2023] [Accepted: 06/19/2023] [Indexed: 08/03/2023] Open
Abstract
BACKGROUND Oligometastatic disease in prostate cancer (PCa) is a challenging clinical scenario encountered more frequently with the widespread adoption of PSMA-PET. SBRT aims to defer androgen deprivation and may deliver sustained biochemical failure (BF) free survival in selected patients. Little long-term data is currently available regarding the effectiveness of this approach. METHODS A retrospective single institution study of PSMA-PET directed SBRT without initial ADT for oligo-metachronous PCa. Median dose/fractionation was 24 Gy in 2# to bones and 30 Gy in 3# to lymph nodes. The primary endpoint was time to BF (PSA + 0.2 ug/L above nadir). Secondary endpoints included time to ADT for relapse (i.e. palliative ADT), BF defined as PSA nadir + 2 ug/L, toxicity, patterns of failure and survival. Patients were excluded if they received ADT with their SBRT, had short disease-free interval, or > 3 metastases on PSMA-PET. RESULTS 103 patients treated from November-2014 to December-2019 were analysed from our prospective database. Median follow-up was 5 years. 64 patients were treated for nodal only disease, 35 bone only and 4 mixed. 15% were free of any BF at 5 years with median time to BF of 1.1 years. 32% (33/103) of patients had further curative-intent radiation treatment following their first BF after SBRT, including subsequent SBRT. Eight patients underwent potentially curative treatment for their second or third relapse. Allowing for salvage treatment, 29/103 (28%) were biochemically disease free at last follow up. At 5 years, 39% of patients had never received any ADT and 55% had not started ADT for relapse with a median time to ADT for relapse of 5.5 years. There were 2 grade 3 toxicities (rib fracture and lymphoedema), and no local failures. CONCLUSION PSMA-PET guided SBRT for oligo-metachronous PCa recurrence in appropriately triaged patients results in excellent local control, low toxicity and over 50% ADT free at 5 years.

Abstract
Abstract
Aim
Surgical site infection increases with BMI with values ranging from 20% to greater than 40%. There are increasing numbers of obese patients (BMI >30) undergoing transplants and this audit aims to review the incidence and grade of surgical site infection (SSI) of renal transplant recipients stratified by BMI.
Method
65 renal transplants were performed between April 2020-March 2021 with 58 kidneys from deceased donors and 7 kidneys from live donors. A retrospective review of clinical attendances, GP letters, prescriptions, imaging, and re-admissions was completed. Nearly one-third of the patients had pre-transplant diabetes (32%), and their median BMI was 28 (range 19–40.7). The incidence of SSI was reported after 3 months follow up and graded using the Clavien-Dindo Classification.
Results
The overall rate of SSI was 15%. SSI was 12.8% in patients with BMI<30, 15.8% in BMI 30–34.9, 33.3% in BMI 35–35.9, and 0 in BMI>40 (only one recipient). There was no significant correlation between diabetes and SSI, with 19% of SSI reported in diabetic patients versus 14% in patients without diabetes (p-value=0.7). Two patients had a Clavien-Dindo grade I infection, 1 grade II, and 7 Grade III, with no grade IV or V SSI. No patients required operative management of SSI.
Conclusions
The overall rates of SSI stratified by BMI were within expected limits. Diabetes was not an independent predictor of SSI. No complication required general anesthesia or surgical treatment. When SSI did occur in obese patients it did cause considerable morbidity through number of attendances for dressing changes over 3 months.

Abstract
Abstract
Aim
Infection is a significant cause of morbidity in kidney transplantation, and it is believed that an increased cold ischemic time is an independent risk factor. Identification of common pathogens in perfusion fluids, as well as the safe limit of cold ischaemic time can be used to reduce the risk of postoperative complications. There are currently no guidelines for prophylactic antibiotics.
Method
This is a retrospective review of the microbiological analysis of kidney perfusion fluids samples for a recipient transplant between 2017–2020. 100 patients were identified in this time period and this data was compared against the cold ischaemic time of the donor kidney.
Results
23% (22/96) samples were positive for bacteria with the majority being gram positive cocci. The most common bacteria grown was Coagulase Negative Staphylococcus (44% - 11/25). However, a broad spectrum of bacteria was grown including Hafnia, Pseudomonas, Klebsiella, Kocuria and E-coli. 3% (3/96) of samples grew two different species of bacteria.
The mean cold ischemic time for all transplants was 799 minutes with a range of 281–1618 minutes. The mean for infected samples was 935 mins with a range of 645–1410. Samples that grew 2 bacteria had a range of 913–941 mins.
Conclusions
There is potential to reduce the risk of infection with the use of broad-spectrum induction antibiotics and it is important that potential bacterial species and common resistance profiles are covered. There is a possible correlation between increased cold ischaemic time and bacterial growth in perfusion fluid however further research is warranted.

Making community pharmacies psychologically informed environments: a pilot study to improve delivery of care for people with a drug problem. INTERNATIONAL JOURNAL OF PHARMACY PRACTICE 2022.

Abstract
Introduction Community pharmacies are key in the delivery of care to people who use drugs (PWUD), providing specialist harm reduction, and treatment interventions such as naloxone, Injecting Equipment Provision and opiate replacement treatment. PWUD are disproportionately burdened with mental ill-health and frequently report trauma history which impacts on engagement. A successful approach in the homeless sector, is that of Psychologically Informed Environments (PIE). The core elements of a PIE are: creating a space which engenders a sense of safety and wellbeing; reflective practice so staff can develop a shared model of working; training and support for staff; and considering the therapeutic aspects of service provision to vulnerable people (1). Aim This pilot study tested training pharmacy staff in applying a psychologically informed environments approach to improve the delivery of care to PWUD. Methods Three pharmacies were recruited from those with high involvement with PWUD. A range of location and type of pharmacy were included. Whole pharmacy teams were invited to an evening training session. Bespoke training was provided by clinical psychologists with PIE expertise. Training was assessed by anonymous quantitative questionnaires using rating scales. Changes in the attitudes of staff were assessed by questionnaire before and 6 months after training. Descriptive statistics were applied. Qualitative interviews with staff at 6 months (planned for 3 months) explored what changes, were made after PIE training to adapt the delivery of care. The study used peer researcher-led telephone interviews for patient/client feedback on observed changes and experiences in participating pharmacies. Recruitment was via the three pharmacy teams due to covid restrictions. Thematic analysis was applied to qualitative data. Normalisation Process Theory provided a framework for assessing change. Results Three pharmacies (16 staff) participated. Training evaluation was positive; all participants rating training structure and delivery as very good or excellent. Covid-19 lockdowns restricted follow-up data collection which took place at six months rather than three. Attitude scores were positive (>0) for all participants at baseline (median 15.0) increasing to 20.0 at 6 months. This was not statistically significant (S=4, p=0.549). Staff interviews revealed training had encouraged staff to reflect on communication and considered the impact of current practice which could be discriminatory e.g. their use of first names, use of private areas and level of explanation to people. The increased mental health challenges for patients from Covid-19 restrictions gave an opportunity for staff to apply their new skills to this patient group and others who were struggling with isolation, as staff across pharmacies noted mental health challenges for patients. Five patients from two pharmacies were interviewed but time delays in data collection meant changes in delivery of care were difficult to recall. Conclusion The study was limited by small sample size and covid-related delays. However, findings indicated that training whole pharmacy teams in PIE was well received and justifies a larger study. The approach allowed staff to reflect on practice and identify previous, potentially discriminatory practice. The importance of clear and compassionate communication was evident.

Abstract
BACKGROUND The incidence of hospital-treated concussion is 100-300/100,000 person years. Reporting of long-lasting post-concussion symptoms (PCS) is estimated at 5-15%. Attachment insecurity is a potential vulnerability factor for physical illness and poorer disease outcomes in general. This study aimed to explore associations between attachment insecurity and PCS in young people sustaining a concussion. METHODS This cross-sectional study was embedded in a cohort of 15-30-year-old patients (n = 3080) 3 months after sustaining a concussion. Data were obtained from a database and questionnaires. PCS were measured by the Rivermead Post-Concussion Symptoms Questionnaire and attachment dimensions (anxiety and avoidance) by the Experiences in Close Relationships-Relationship Structures Questionnaire. Multiple linear regression models were performed to investigate the association between the attachment dimensions and PCS with adjustment for demographic, injury-related and psychological factors and with additional testing for interaction between the attachment dimensions. RESULTS In the final study sample, comprising 973 patients (31.6%), we found an interaction between the attachment dimensions. Hence, the effect of attachment anxiety on PCS was statistically insignificant at low avoidance (25th percentile) but significant at high avoidance (75th percentile, β = 0.64 (95%CI: 0.02; 1.26)), whereas the effect of attachment avoidance was significant regardless of level of attachment anxiety (25th percentile, β = 1.09 (95%CI: 0.18; 2.01); 75th percentile, β = 2.71 (95%CI: 1.80; 3.61)). CONCLUSION Attachment insecurity, especially characterised by high avoidance in combination with high anxiety, also called fearful attachment, is associated with PCS. Considering the attachment perspective can potentially improve health care for this patient group.

Abstract
Aim
To highlight the importance of appropriate imaging modalities for abnormal clinical presentations.
Method
Xyo woman presented with severe right upper-quadrant pain to the emergency department. Prior history of colicky abdominal pain for 1 year, right-sided nephrectomy and hypertension. She stated that the current epsiode of pain was the worst so far, becoming more persistent, prompting her to call an ambulance. Cholecystitis was suspected, so a Computed Tomography abdomen/pelvis was performed. A dilated, inflamed gallbladder was noted in contact with the right psoas major, with what appeared to be an abscess in the right psoas major.
Results
A Magnetic Resonance Cholangiopancreatography was performed, which demonstrated that the aforementioned abscess was in fact a large cavity within the psoas major, containing up to 15 gallstones. Cholelithiasis was also seen, with common bile duct dilatation and evidence of a common bile duct stone. An Endoscopic Retrograde Cholangiopancreatography was performed, and X recovered well post-procedure with analgesia and antibiotics.
Conclusions
Acute cholecystitis/intra-abdominal gallstones may result in abscess/cavity formations and abnormal biliary clinical presentations. It is important therefore to fully investigate abnormal hepatobiliary imaging with multiple imaging modalities to allow for accurate diagnosis and appropriate further management of presentations.

Abstract
UNLABELLED This paper studies the US and global economic fundamentals that exacerbate emerging stock markets volatility and can be considered as systemic risk factors increasing financial stability vulnerabilities. We apply the bivariate HEAVY system of daily and intra-daily volatility equations enriched with powers, leverage, and macro-effects that improve its forecasting accuracy significantly. Our macro-augmented asymmetric power HEAVY model estimates the inflammatory effect of US uncertainty and infectious disease news impact on equities alongside global credit and commodity factors on emerging stock index realized volatility. Our study further demonstrates the power of the economic uncertainty channel, showing that higher US policy uncertainty levels increase the leverage effects and the impact from the common macro-financial proxies on emerging markets' financial volatility. Lastly, we provide evidence on the crucial role of both financial and health crisis events (the 2008 global financial turmoil and the recent Covid-19 pandemic) in raising markets' turbulence and amplifying the volatility macro-drivers impact, as well.

Abstract
This article reports on the research by a working group, comprising members from the Association of University Radiation Protection Officers, on the radiation safety culture in the UK higher education, research and teaching (HERT) sectors. The impetus for this research arises from the work of the International Radiation Protection Association and their emphasis that embedding radiation safety culture within an organisation is the most effective way of delivering the standards of radiation safety and security that society expects. The deficiency in radiation safety culture has been a large contributor to major nuclear disasters, such as Chernobyl and Fukushima Daiichi. The working group designed an online survey aimed at higher education students, higher education academics, and researchers. The survey did not try to obtain an indication of safety performance, but of people's views on behaviours and attitudes of radiation safety that reflect the current radiation safety culture in their organisation. The findings of the survey are reported in this article along with a discussion of the analysis and recommendations for improving radiation safety culture. The responses from the survey strongly indicate that the radiation safety culture in UK HERT sectors has worrying shortfalls, particularly in communication and training.

Abstract
INTRODUCTION In the surveillance of children with cerebral palsy, the measurement of migration percentage is used to identify children at risk of hip dislocation. Early identification of children at risk facilitates early intervention with less invasive surgical procedures to prevent further deterioration. The aim of this study is to evaluate the safety of the measurements of migration percentage for surveillance in cerebral palsy by extended-role radiographers by evaluating the reliability and validity of measurements performed by these professionals. METHODS A sample of thirty pelvic x-rays were selected from the local cerebral palsy database. A range of hip displacement was selected including some challenging borderline x-rays. All ten extended-role radiographers completed measurements using TraumaCAD which were repeated at a minimum of 4 weeks. Inter-rater and intra-rater reliability was calculated using intraclass correlation coefficients. The accuracy and safety of the system was evaluated by converting measurements into referral categories (red, amber or green) and cohen's kappa was calculated when categories were compared to measurements to orthopaedic surgeon RESULTS: The inter-rater reliability between radiographers was 0.938 (95% CI 0.914-0.991). The intra-rater reliability was 0.941 (95% CI 0.931-0.949). The percentage agreement was 94.8% for green, 93.8% for amber and 98.2% for red hips. The weighted kappa value was 0.923 (95% CI 0.889-0.957). CONCLUSION The reliability and accuracy of radiographer measurement of migration percentage is excellent. It is safe for radiographers to calculate the migration percentage using semi-automated software for the surveillance of children with cerebral palsy. IMPLICATIONS FOR PRACTICE We recommend the measurement of migration percentage may be performed by extended-role radiographers to deliver accurate and reliable measurements for use in cerebral palsy surveillance.

Abstract
Many bottlenecks in drug discovery have been addressed with the advent of new assay and instrument technologies. However, storing and processing chemical compounds for screening remains a challenge for many drug discovery laboratories. Although automated storage and retrieval systems are commercially available for medium to large collections of chemical samples, these samples are usually stored at a central site and are not readily accessible to satellite research labs. Drug discovery relies on the rapid testing of new chemical compounds in relevant biological assays. Therefore, newly synthesized compounds must be readily available in various formats to biologists performing screening assays. Until recently, our compounds were distributed in screw cap vials to assayists who would then manually transfer and dilute each sample in an “assay-ready” compound plate for screening. The vials would then be managed by the individuals in an ad hoc manner. To relieve the assayist from searching for compounds and preparing their own assay-ready compound plates, a newly customized compound storage system with an ordering software application was implemented at our research facility that eliminates these bottlenecks. The system stores and retrieves compounds in 1 mL-mini-tubes or microtiter plates, facilitates compound searching by identifier or structure, orders compounds at varying concentrations in specified wells on 96- or 384-well plates, requests the addition of controls (vehicle or reference compounds), etc. The orders are automatically processed and delivered to the assayist the following day for screening. An overview of our system will demonstrate that we minimize compound waste and ensure compound integrity and availability. (JALA 2004;9:123-7)

Abstract
The OPCS scales of disability were developed as a survey tool to estimate the prevalence of disability amongst adults in the UK. This study evaluates the use of the OPCS scales in a clinical setting. A total of 265 patients attending a rehabilitation unit and wheelchair centre were assessed. The OPCS scales were validated against the standard Barthel Index and sensitivity to change over time was examined. An inter-rater reliability study was also performed. The results showed good correlation between the OPCS scales and Barthel Index (0.82, p < 0.001, n = 265) and it was shown that the OPCS scales were sensitive to clinical change over a six-month period. Inter-rater reliability was also good (0.96, p < 0.001, n = 120). The 95% confidence limits were also examined. The 'ceiling' effect of the Barthel Index is not found in the OPCS scales of disability. The results of the study support further use of the OPCS scales and suggest that it has a place in the assessment of rehabilitation outcome.

Abstract
Wheelchairs issued on prescription are of a generic design and only accommodate individual requirements to a limited extent. Basic maintenance, for example use of the recommended tyre pressure to minimize rolling resistance, may therefore help reduce the energy expenditure of propulsion for patients issued with these standard wheelchairs. In a community survey of 145 wheelchairs (99 self-propulsion and 46 attendant-propulsion models) we found that only 4% of the self-propulsion wheelchairs had the recommended tyre pressure. Overall, 14% had pressures ≤ 5 pounds per square inch (psi) and a further 37% were between six and 15 psi. In 10 able-bodied subjects, we also found a significant rise (p < 0.01) of approximately 20% in the physiological energy expenditure of self-propelling a standard wheelchair, as assessed by minute ventilation, gas exchange and heart rate, when tyre pressure was reduced from 45 psi to ≤ 5 psi. Introduction of solid synthetic tyres, therefore, will have considerable advantages for patients who do not maintain even the lowest pressure needed to minimize energy expenditure. Use of this material for tyres of self-propulsion wheelchairs is also highly desirable.

Abstract
This study aimed to assess the value of periodic review by an occupational therapist (OT) of elderly patients with rheumatoid arthritis (RA). Twenty-four patients aged over 65 years who had longstanding RA and had had at least one previous contact with an OT completed a modified health assessment questionnaire (HAQ)1.2 to give an assessment of their self perceived functional ability then had a formal OT assessment. Two months later the patients completed a second HAQ to assess the effect of the OT assessment and assistance. Only three of the 24 patients were felt by the OT to have no need of intervention by her; 17 of the patients felt that the OT contact had been useful. Possible intervention to improve quality of life was not predicted by the patient's perception of limitations nor by the HAQ score. There were no significant changes in HAQ scores despite OT assessment and intervention. Other assessments of disability or wellbeing merit investigation in the context of OT intervention but the need for OT review of elderly patients with RA is clear.

Abstract
A prospective study of morbidity among 55 lower limb amputees was carried out by multiprofessional teams in two rehabilitation units in Lothian. The aim of treatment was the restoration of independence rather than concentration solely on walking training, although this was important in that 90% of patients were fitted with a temporary artificial limb. The problems and progress of these patients varied, but 90% returned successfully to the community where they made moderate demands on community services. Important differences in professional assessment were noted. The physiotherapists judged that 73% of the patients studied were mobile without help prior to discharge, whereas nurses placed only 46% of the same group at this level of independence. The occupational therapist assessed more of the patients (68%) as fully independent in selfcare than the nurses (44%). This difference between what the patient can do when assessed in therapy and what he actually does when observed in the ward was resolved in case conferences. Forty of the 46 patients who survived for one year replied to a postal questionnaire. Of these, 29 reported independence in mobility indoors and 20 reported total independence in activities of daily living, indicating that as a group they had achieved the level of function predicted. Only two patients required institutional care; two patients (17% of those previously employed) had returned to work. Successful rehabilitation of patients with multiple problems requires a holistic approach. This study demonstrates the need for multiprofessional case discussions so that appropriate decisions on discharge and future management can be made.

Abstract
Few studies have reported on sexually transmitted infections at the US–Mexico border, so the prevalence of Chlamydia trachomatis in this population remains uncertain. This binational project investigated the prevalence of, and risk factors for, C. trachomatis among women along the Arizona, US–Sonora, Mexico border. Women who self-referred for routine gynaecological care were invited to complete an interviewer-administered questionnaire and to undergo a Pap smear, C. trachomatis test, and HPV test. In 2270 women, C. trachomatis prevalence overall was 8.2% as measured by hybrid capture and 2.6% by enzyme immunoassay. Infection was associated with young age, a history of new sexual partner(s) in the previous three months, HPV infection, and proximity of clinic to the international border. Antibiotic use in the previous 30 days was associated with decreased odds of infection. Women in Arizona–Sonora border communities are at increased risk for C. trachomatis infection compared to women attending clinics in non-border locations.

Abstract
OBJECTIVE Tissue uptake of 2-deoxy-2-fluorine-18 fludeoxyglucose ((18)F-FDG) is routinely quantified as standardized uptake value (SUV), which in general is the fraction (F) of administered activity per millilitre of tissue multiplied by an index of body size, usually weight (W), i.e. F/ml × W = SUV or F/ml = SUV × (1/W). Other indices have been suggested as preferable to W, especially lean body mass (LBM) and body surface area (BSA). The second equation mentioned above shows that the reciprocal of the ideal index should correlate closely with F/ml and give a regression line through the origin. The purpose of this study was to determine which of these three indices best meets these criteria. METHODS Data were evaluated from 49 males and 51 females undergoing routine (18)F-FDG positron emission tomography/CT. A 3 cm diameter region of interest was drawn over the liver and F/ml recorded. LBM and BSA were estimated from height and weight. RESULTS Based on all patients, the reciprocals of the three indices gave similar correlation coefficients with F/ml, but only 1/LBM gave regressions close to the origin. Intercepts were significantly higher for females for 1/W and 1/BSA, consistent with females having more body fat, but there was no significant difference with 1/LBM. CONCLUSION LBM is the best index on which to base SUV because adipose tissue accumulates less (18)F-FDG than other soft tissues. ADVANCES IN KNOWLEDGE The value of this study lies in its use of a novel, more rational approach than previously to confirm that SUV should be based on LBM.

Abstract
OBJECTIVE This study aimed to monitor the microbiological effect of cleaning near-patient sites over a 48-hour period with a novel disinfectant, electrolyzed water. SETTING One ward dedicated to acute care of the elderly population in a district general hospital in Scotland. METHODS Lockers, left and right cotsides, and overbed tables in 30 bed spaces were screened for aerobic colony count (ACC), methicillin-susceptible Staphylococcus aureus (MSSA), and methicillin-resistant S. aureus (MRSA) before cleaning with electrolyzed water. Sites were rescreened at varying intervals from 1 to 48 hours after cleaning. Microbial growth was quantified as colony-forming units (CFUs) per square centimeter and presence or absence of MSSA and MRSA at each site. The study was repeated 3 times at monthly intervals. RESULTS There was an early and significant reduction in average ACC (360 sampled sites) from a before-cleaning level of 4.3 to 1.65 CFU/cm(2) at 1 hour after disinfectant cleaning ( P < .0001). Average counts then increased to 3.53 CFU/cm(2) at 24 hours and 3.68 CFU/cm(2) at 48 hours. Total MSSA/MRSA (34 isolates) decreased by 71% at 4 hours after cleaning but then increased to 155% (53 isolates) of precleaning levels at 24 hours. CONCLUSIONS Cleaning with electrolyzed water reduced ACC and staphylococci on surfaces beside patients. ACC remained below precleaning levels at 48 hours, but MSSA/MRSA counts exceeded original levels at 24 hours after cleaning. Although disinfectant cleaning quickly reduces bioburden, additional investigation is required to clarify the reasons for rebound contamination of pathogens at near-patient sites.

Abstract
Objective To determine the prevalence of traditional cardiovascular risk factors using established definitions in a large cohort of clinically well-characterized primary Sjögren's syndrome (SS) patients and to compare them to healthy controls. Methods Data on cardiovascular risk factors in primary SS patients and controls were collected prospectively using a standardized pro forma. Cardiovascular risk factors were defined according to established definitions. The prevalence of cardiovascular risk factors in the primary SS group was determined and compared to that in the control group. Results Primary SS patients had a higher prevalence of hypertension (28–50% versus 15.5–25.6%; P < 0.01) and hypertriglyceridemia (21% versus 9.5%; P = 0.002) than age- and sex-matched healthy controls. Furthermore, a significant percentage (56%) of hypertensive patients expected to be on antihypertensive treatment according to best practice was not receiving it. Conclusion Primary SS patients are more than 2 times more likely to experience hypertension and hypertriglyceridemia than age- and sex-matched healthy controls. Additionally, hypertension is underdiagnosed and suboptimally treated in primary SS.

Abstract
INTRODUCTION The British Orthopaedic Association/British Association of Plastic, Reconstructive and Aesthetic Surgeons guidelines for the management of open tibial fractures recommend early senior combined orthopaedic and plastic surgical input with appropriate facilities to manage a high caseload. The aim of this study was to assess whether becoming a major trauma centre has affected the management of patients with open tibial fractures. METHODS Data were obtained prospectively on consecutive open tibial fractures during two eight-month periods: before and after becoming a trauma centre. RESULTS Overall, 29 open tibial fractures were admitted after designation as a major trauma centre compared with 15 previously. Of the 29 patients, 21 came directly or as transfers from another accident and emergency deparment (previously 8 of 15). The time to transfer patients admitted initially to local orthopaedic departments has fallen from 205.7 hours to 37.4 hours (p=0.084). Tertiary transferred patients had a longer hospital stay (16.3 vs 14.9 days) and had more operations (3.7 vs 2.6, p=0.08) than direct admissions. As a trauma centre, there were improvements in time to definitive skeletal stabilisation (4.7 vs 2.2 days, p=0.06), skin coverage (8.3 vs 3.7 days, p=0.06), average number of operations (4.2 vs 2.3, p=0.002) and average length of hospital admission (26.6 vs 15.3 days, p=0.05). CONCLUSIONS The volume and management of open tibial fractures, independent of fracture grade, has been directly affected by the introduction of a trauma centre enabling early combined senior orthopaedic and plastic surgical input. Our data strongly support the benefits of trauma centres and the continuing development of trauma networks in the management of open tibial fractures.
