ASSOCIATION OF MPV AND RDW WITH DISEASE ACTIVITY IN PATIENT WITH RHEUMATOID ARTHRITIS.

Rheumatoid arthritis (RA) is a chronic autoimmune disorder characterized by inflammation of the synovial joints. Disease activity assessment plays a crucial role in guiding treatment decisions and monitoring disease progression in RA patients. Thus, the current study examines the association between Mean Platelet Volume (MPV), Red Cell Distribution Width (RDW), and disease activity in RA patients. A total of 100 patients were included following the inclusion and exclusion criteria. All participants underwent physical examination and laboratory tests. Disease activity was assessed using the Disease Activity Score 28 (DAS28). The cut-off levels for RDW and MPV were 14.8 and 11.25, respectively. However, a significant association was observed between RDW levels and DAS28, indicating that the group with RDW ≤14.8% displayed higher DAS compared to the RDW >14.8% group. Also, MPV levels did not exhibited statistically significant variations. RDW levels did not show significant disparities among patients with different comorbidities. There is a significant correlation exists between RDW and disease activity in RA exists. Moreover, RDW can be utilized in clinical settings to monitor disease activity effectively. Since RDW is routinely included in standard blood tests, it is cost-effective and more convenient for treating RA cases.

TRIGLYCERIDE - GLUCOSE INDEX, REMNANT CHOLESTEROL AND COMMON CAROTID ARTERY INTIMA-MEDIA THICKNESS AS AN ATHEROSCLEROTIC MARKER IN ISCHEMIC STROKE PATIENTS.

Ischemic stroke (IS) is a major global health concern, often resulting from atherosclerosis and insulin resistance (IR). The triglyceride-glucose index (TyG index), remnant cholesterol (RC), and common artery intima-media thickness (CIMT) are potential markers for assessing atherosclerosis and cardiovascular risk in IS patients. A cross-sectional study was conducted to investigate the association between TyG index, RC, CIMT, and IS in adult patients recruited from a hospital. Demographic, clinical, and laboratory data were collected, and statistical analysis was performed. The study included 50 participants with a balanced gender distribution and a mean age of 57.64 years. Laboratory characteristics showed notable values, and CIMT > 0.6 mm was associated with higher NIH Stroke Scale scores. RC exhibited significant correlations with age, CIMT, lipid profile, and TyG index. The study highlights the potential of TyG index, RC, and CIMT as atherosclerotic markers in IS patients. Favorable prognostic outcomes were observed, emphasizing the importance of early diagnosis and management to improve patient outcomes.

National survey of occupational advice for lower limb arthroplasty patients.

BACKGROUND: Little is known what advice or support patients are given about return to work (RTW) after hip or knee replacement surgery. AIMS: This study aims to understand the delivery, timing and content of 'RTW' advice currently delivered by surgical teams offering hip and knee replacements across the UK. METHODS: National online survey exploring five specific areas relating to 'RTW' advice: (i) timings of interactions between hospital orthopaedic teams and patients prior to surgery, (ii) routine delivery of 'RTW' advice, (iii) methods used to deliver 'RTW' advice, (iv) confidence delivering advice and (v) need for an occupational 'RTW' advice intervention. RESULTS: A total of 152 participants including surgeons, physiotherapists, occupational therapists and nurses from 59 different public and private health providers responded. Only 20% (n = 30) of respondents reported that working patients were identified as a specific subgroup in need of additional support. Overall, 62% (n = 92) stated that they did not routinely offer 'RTW' advice. When given, 'RTW' advice was almost always verbal, generic advice using blanket timescales and based on the respondent's anecdotal experience rather than the patients individualized needs. Overall, 116 (78%) felt an occupational advice intervention was needed. CONCLUSIONS: This national survey demonstrated wide variation in the timing, content and delivery of information and advice for patients in work and intending to RTW after hip and knee replacement surgery. Current RTW advice provided to hip and knee replacement patients is inadequate.

Impact of a national enhanced recovery after surgery programme on patient outcomes of primary total knee replacement: an interrupted time series analysis from "The National Joint Registry of England, Wales, Northern Ireland and the Isle of Man".

OBJECTIVE: We aimed to test whether a national Enhanced Recovery After Surgery (ERAS) Programme in total knee replacement (TKR) had an impact on patient outcomes. DESIGN: Natural-experiment (April 2008-December 2016). Interrupted time-series regression assessed impact on trends before-during-after ERAS implementation. SETTING: Primary operations from the UK National Joint Registry (NJR) were linked with Hospital Episode Statistics (HES) data which contains inpatient episodes undertaken in National Health Service (NHS) trusts in England, and Patient Reported Outcome Measures (PROMs). PARTICIPANTS: Patients undergoing primary planned TKR aged ≥18 years. INTERVENTION: ERAS implementation (April 2009-March 2011). OUTCOMES: Regression coefficients of monthly means of Length of stay (LOS), bed day costs, change in Oxford knee scores (OKS) 6-months after surgery, complications (at 6 months), and rates of revision surgeries (at 5 years). RESULTS: 486,579 primary TKRs were identified. Overall LOS and bed-day costs decreased from 5.8 days to 3.7 and from £7607 to £5276, from April 2008 to December 2016. Oxford knee score (OKS) change improved from 15.1 points in April 2008 to 17.1 points in December 2016. Complications decreased from 4.1 % in April 2008 to 1.7 % in March 2016. 5-year revision rates remained stable at 4.8 per 1000 implants years in April 2008 and December 2011. After ERAS, declining trends in LOS and bed costs slowed down; OKS improved, complications remained stable, and revisions slightly increased. CONCLUSIONS: Different secular trends in outcomes for patients having TKR have been observed over the last decade. Although patient outcomes are better than a decade ago ERAS did not improve them at national level.

Shorter sleep duration is associated with higher energy intake and an increase in BMI z-score in young children predisposed to overweight.

BACKGROUND: Inadequate sleep has been shown to be a contributor to obesity in both children and adults. Less evidence is available for toddlers and among those with higher obesity risk. The objective of this study was to examine the relationship between sleep patterns and body weight development in a group of young obesity-predisposed children, and to assess whether intakes of energy or macronutrients mediate this relationship. METHODS: Participants included 368 Danish children aged 2-6 years from the Healthy Start Study, a 1.3 year randomised controlled intervention trial. Sleep habits were measured using a 7-day sleep diary. Multivariate linear regression with adjustment for confounders was used to assess the association of sleep duration and sleep variability with 1.3 year changes (Δ) in body mass index (BMI) z-score from baseline to follow-up. RESULTS: The average nighttime sleep duration was 10.7 h (range 8.8-12.5 h). After controlling for potential confounders, a significant inverse association between nighttime sleep duration and ΔBMI z-score (ß=-0.090, P=0.046) was observed. This relationship was mediated by energy intake, with all macronutrients contributing to this mediation effect. No associations were found for sleep variability and ΔBMI z-score but baseline intake of added sugars and sugary beverages were positively associated with sleep variability. CONCLUSION: Shorter sleep duration, mediated by energy intake in early in life, seems a risk factor for weight gain among young obesity-predisposed children.

Validity of short food questionnaire items to measure intake in children and adolescents: a systematic review.

BACKGROUND: Short food questions are appealing to measure dietary intakes. METHODS: A review of studies published between 2004 and 2016 was undertaken and these were included in the present study if they reported on a question or short item questionnaire (≤50 items, data presented as ≤30 food groups) measuring food intake or food-related habits, in children (aged 6 months to 18 years), and reported question validity or reliability. Thirty studies met the inclusion criteria. RESULTS: Most questions assessed foods or food groups (n = 29), with the most commonly assessed being fruit (n = 22) or vegetable intake (n = 23), dairy foods and discretionary foods (n = 20 studies each). Four studies assessed food habits, with the most common being breakfast and meal frequency (n = 4 studies). Twenty studies assessed reliability, and 25 studies determined accuracy and were most commonly compared against food records. Evaluation of question performance relied on statistical tests such as correlation. CONCLUSIONS: The present study has identified valid and reliable questions for the range of key food groups of interest to public health nutrition. Questions were more likely to be reliable than accurate, and relatively few questions were both reliable and accurate. Gaps in repeatable and valid short food questions have been identified that will provide direction for future tool development.

A reduction for spiking integrate-and-fire network dynamics ranging from homogeneity to synchrony.

In this paper we provide a general methodology for systematically reducing the dynamics of a class of integrate-and-fire networks down to an augmented 4-dimensional system of ordinary-differential-equations. The class of integrate-and-fire networks we focus on are homogeneously-structured, strongly coupled, and fluctuation-driven. Our reduction succeeds where most current firing-rate and population-dynamics models fail because we account for the emergence of 'multiple-firing-events' involving the semi-synchronous firing of many neurons. These multiple-firing-events are largely responsible for the fluctuations generated by the network and, as a result, our reduction faithfully describes many dynamic regimes ranging from homogeneous to synchronous. Our reduction is based on first principles, and provides an analyzable link between the integrate-and-fire network parameters and the relatively low-dimensional dynamics underlying the 4-dimensional augmented ODE.

You are what you choose to eat: factors influencing young adults' food selection behaviour.

BACKGROUND: Young or 'emerging' adulthood (ages 18-24 years) is a life-stage characterised by rapid weight gain, particularly among those born in recent decades, when environments have become saturated with cheap, highly palatable, processed foods. Although intervening in the immediate food environments of emerging adults is indicated, little is known about the factors influencing their food selection. The present study aimed to: (i) measure the relative importance of different influences on foods selected by emerging adults for consumption from a tertiary education setting and (ii) examine whether these influences differ according to gender, adiposity status, perceived stress and dieting or physical activity behaviours. METHODS: An online survey was administered with 112 emerging adults aged 19-24 years assessing demographics, perceived stress, dieting, physical activity and influences on food selection. Adiposity indicators (body mass index and waist circumference) were measured. Analyses compared the importance of influences on food selection by gender, adiposity, perceived stress, dieting and physical activity. RESULTS: Taste was the most important influence on food selection, followed by convenience (availability), cost, nutrition/health value, smell and stimulatory properties (alertness). Participants with an elevated waist circumference selected foods to help them cope with stress and control their weight. Those reporting a higher level of physical activity placed greater importance on nutritional/health value of foods but less importance on taste. Female dieters also placed less importance on taste and value for money. CONCLUSIONS: Health promotion strategies addressing tertiary education food environments of emerging adults should ensure the ready availability of tasty and nutritious foods at a low cost.

Liquid versus solid energy intake in relation to body composition among Australian children.

BACKGROUND: The debate about whether energy consumed in liquid form is more obesogenic than energy consumed in solid form remains equivocal. We aimed to evaluate the effects of liquid versus solid energy intake and different beverage types on changes in childhood adiposity. METHODS: Our analyses included 8-year-old Australian children (n = 158) participating in the Childhood Asthma Prevention Study. Dietary information was collected using three 24-h recalls at age 9 years. Multivariate linear regression was used to evaluate the effects of liquid versus solid energy intake and different beverage types on changes in body mass index (BMI) Z-score from ages 8 to 11.5 years (△BMIz(8-11.5y)) and percentage body fat (%BF) at age 11.5 years (%BF(11.5y)). Substitution models were used to evaluate the effects of substituting other beverage types for sugar-sweetened beverages (SSB). RESULTS: Liquid energy intake (1 MJ day(-1)) was more closely associated with both △BMIz(8-11.5y) (ß = 0.23, P = 0.02) and %BF(11.5y) (ß = 2.31%, P = 0.01) than solid energy intake (△BMIz(8-11.5y): ß = 0.12, P = 0.01 and %BF(11.5y): ß = 0.80%, P = 0.07). SSB consumption (100 g day(-1)) was directly associated with △BMIz(8-11.5y) (ß = 0.08, P = 0.02) and %BF(11.5y) (ß = 0.92%, P = 0.004),whereas diet drinks (100 g day(-1) ) were inversely associated with △BMIz(8-11.5y) (ß = 0.18, P = 0.02). Substitution of 100 g of SSB by 100 g of water or diet drink, but not other beverages, was inversely associated with both △BMIz(8-11.5y) and %BF(11.5y) (P < 0.01). CONCLUSIONS: Our findings indicate that liquid energy is more obesogenic than solid energy. In particular, SSB, but not other beverage types, are a significant predictor of childhood adiposity and replacing SSB with water can have long-term beneficial effects on childhood adiposity.

Cemented Thompson's hemiarthroplasty in patients with intracapsular neck of femur fractures: survival analysis of 1,670 procedures.

Cemented Thompson's prostheses have been used to treat elderly patients with displaced intracapsular hip fractures at our two units for the last 15 years, amid growing support for the use of newer implant designs for hip hemiarthroplasty. This provided us with an opportunity to investigate survival of the Thompson's stem in our patients. A retrospective cohort study was set up to review previously collected data on patients who underwent Thompson's hemiarthroplasty over a 7-year period. These were linked to surgical notes, clinical letters and radiographs to record post-operative course and subsequent admissions and procedures. The identifiers were then linked to mortality data from the Office of 'National Statistics. Kaplan-Meier survival analyses were done for implants and patients. A total of 1,632 patients (mean age 82.7 years) underwent 1,670 procedures. Five-year implant survival was 95.4 %. A total of 36 stems were revised, including 14 revisions to total hip arthroplasty and 22 excision arthroplasties. Reasons for revision included infection (2.1 %), dislocation (1.1 %) and aseptic loosening (0.5 %). Symptomatic aseptic loosening and acetabular erosion occurred late (mean time 3.2 and 5.7 years, respectively following surgery). Aseptic loosening and erosion following hemiarthroplasty are relatively late complications.

Misreporting of energy intake in the 2007 Australian Children's Survey: differences in the reporting of food types between plausible, under- and over-reporters of energy intake.

BACKGROUND: Misreporting is common when collecting dietary intake data, although relatively little is known about the types of foods misreported among children. The present study aimed to identify differences in the reporting of food types between plausible and misreporters of energy intake in a national nutrition survey of Australian children. METHODS: Dietary data were collected using a 24-h recall from 4826 children aged 2-16 years who were participating in the 2007 Australian National Children's Nutrition and Physical Activity Survey. Misreporters of energy intake were classified using the Goldberg criteria. Differences in the reporting of a range of food types were examined between plausible, under- and over-reporters. RESULTS: Compared with plausible reporters, under-reporters reported less frequent consumption and smaller quantities of consumption of both core and noncore foods. Older children (self-report) under-reported a larger selection of noncore foods than younger children (parental report). Over-reporters reported similar percentages of consumption of many core and noncore foods, with some exceptions. The quantities consumed by over-reporters were generally much larger and this was evident in younger and older children. Compared with plausible reporters, under-reporters had significantly higher intakes of protein and starch but lower intakes of sugar and fat, as percentage energy, than plausible reporters, whereas over-reporters had higher fat and lower carbohydrate intakes. CONCLUSIONS: Differences in the reporting of food types were common between plausible, under- and over-reporters of energy intake by children (or their parents) and were not restricted to noncore foods.

Higher regular fat dairy consumption is associated with lower incidence of metabolic syndrome but not type 2 diabetes.

BACKGROUND AND AIMS: Limited evidence suggests habitual dairy consumption to be protective against metabolic syndrome (MetSyn) and type 2 diabetes among older adults. We assessed the association of baseline consumption of dairy products with the incidence of MetSyn and type 2 diabetes among a cohort of Australian adults aged 49 years and over. METHODS AND RESULTS: A validated 145-item semi-quantitative food frequency questionnaire was used to assess food and nutrient intake at baseline. Ten-year incidence of MetSyn and type 2 diabetes were obtained from 1807 and 1824 subjects respectively. Odds ratios (OR) were calculated by discrete time logistic regression modelling. Compared with subjects in the lowest intake quartile of regular fat dairy products, those in the highest quartile had a 59% lower risk of MetSyn (multivariate adjusted OR: 0.41; 95% CI: 0.23-0.71; p(trend) = 0.004), after adjustment for risk factors. Among obese subjects, an association between a high intake of regular fat dairy foods and reduced risk of type 2 diabetes was also found (age and sex adjusted OR 0.37; 95% CI: 0.16-0.88; p(trend) = 0.030), but the association did not persist after adjustment for additional confounders. There was no association between total dairy consumption and risk of MetSyn or type 2 diabetes. CONCLUSIONS: We found an inverse association between regular fat dairy consumption and risk of MetSyn among Australian older adults. Further studies are warranted to examine the association between weight status, dairy consumption and risk of type 2 diabetes.

A review of custom implants for glenoid bone deficiency in reverse shoulder arthroplasty.

Reverse Total Shoulder Arthroplasty is being increasingly performed, with indications in both elective and trauma settings. Accordingly, there are an increasing number of revision cases where glenoid bone loss is a concern. There are well recognised surgical techniques for dealing with mild to moderate glenoid wear, including eccentric reaming and impaction grafting. In cases of severe wear or uncontained glenoid defects these may not be suitable, and the surgeon may look to a customised implant to deal with such bone loss. There are several implant manufacturers who currently market and produce patient specific instrumentation and customised glenoid baseplates to achieve the best possible fixation in cases of severe bone loss. This article outlines some examples of custom implants currently available to surgeons, and the process by which they may be procured and used. Implant and surgical considerations, and key aspects of surgical technique are also covered. Literature on outcomes and complications following custom shoulder arthroplasty shows promising results, but at present is limited to relatively small case series with no long-term outcome data.

Factor structure of the Oxford Shoulder Score: secondary analyses of the UK FROST and PROFHER trial populations.

AIMS: Frozen shoulder and proximal humeral fracture can cause pain, stiffness and loss of function. The impact of these symptoms on patients can be measured using the comprehensively validated, 12-item Oxford Shoulder Score (OSS). Evidence suggests that pain and function may have a differential impact on patients' experience of shoulder conditions, and this may be important for clinical management. We therefore explored the factor structure of the OSS within the UK FROST and PROFHER trial populations. METHODS: We performed exploratory factor analysis (EFA), followed by confirmatory factor analysis (CFA), on baseline UK FROST data from 490 of the 503 trial participants. Data at 6 months post-randomisation were used for 228 of the 250 participants for the PROFHER trial. RESULTS: UK FROST factor extraction results, using Velicer's Minimum Average Partial and Horn's Parallel Analysis tests, suggested a unifactorial solution, but two factors were weakly indicated by the less reliable 'Kaiser's eigenvalue > 1' and scree tests. We explored this further using EFA. Eight items (2 to 7, 9 and 10) loaded onto a 'Function' factor, three on a 'Pain' factor (1, 8 and 12) and item 11 cross-loaded. However, one- and two-factor models were rejected in CFA. Factor extraction of PROFHER data at 6 months demonstrated a single first-order factor solution, which was also subsequently rejected in CFA. CONCLUSION: Insufficient evidence was found, within the constraints of the data available, to support the use of 'Pain' and 'Function' sub-scales of the OSS in either patient population.

Haem Iron Intake Is Associated with Increased Major Adverse Cardiovascular Events, All-Cause Mortality, Congestive Cardiac Failure, and Coronary Revascularisation in Older Men: The Concord Health and Ageing in Men Project.

BACKGROUND: Nutritional intake can influence major adverse cardiovascular events (MACE). Dietary iron is found in two forms: haem-iron (HI) only found in animal sources and non-haem iron (NHI) present mostly in plant sources. OBJECTIVE: We evaluated the associations between dietary iron intakes with MACE and iron status biomarkers. DESIGN: Prospective cohort study. SETTING: The Concord Health and Ageing in Men Project, Sydney, Australia. PARTICIPANTS: 539 community-dwelling older Australian men aged 75 years and older. METHODS: Men underwent nutritional assessment using a validated diet history questionnaire. Entries were converted to food groups and nutrients. The dietary calculation was used to derive HI and NHI intakes from total iron intakes. Analyses of iron intakes with iron status biomarkers were conducted using linear regression, and with MACE and individual endpoints were conducted using Cox regression. Five-point MACE comprised of all-cause mortality, myocardial infarction (MI), congestive cardiac failure (CCF), coronary revascularisation, and/or ischaemic stroke. Four-point MACE included the four endpoints of MI, CCF, coronary revascularisation, and/or ischaemic stroke, and excluded all-cause mortality. RESULTS: At a median of 5.3 (4.6 - 6.3) years follow-up, the incidences were: 31.2% (n = 168) five-point MACE, 17.8% (n = 96) four-point MACE excluding all-cause mortality, 20.1% (n = 111) all-cause mortality, 11.3% (n = 61) CCF, and 3.1% (n = 15) coronary revascularisation. In adjusted analyses, higher HI intake (per 1mg increment) was associated with increased five-point MACE (HR: 1.45 [95% CI: 1.16, 1.80, P = .001]), four-point MACE excluding all-cause mortality (HR: 1.64 [95% CI: 1.26, 2.15, P <.001]), all-cause mortality (HR: 1.51 [95% CI: 1.15, 1.99, P = .003]), CCF (HR: 2.08 [95% CI: 1.45, 2.98, P <.001]), and coronary revascularisation (HR: 1.89 [95% CI: 1.15, 3.10, P = .012]). Compared with the bottom tertile of NHI intake, the middle tertile of NHI intake was associated with reduced risk of all-cause mortality (HR: 0.56 [95% CI: 0.33, 0.96, P = .035]). Total iron intake was not associated with MACE and individual endpoints. Dietary iron intakes were not associated with serum iron and haemoglobin. CONCLUSION: Higher haem iron intake was independently associated with increased risks of five-point MACE, four-point MACE excluding all-cause mortality, all-cause mortality, CCF, and coronary revascularisation in older men over 5 years.

Physiotherapy for primary frozen shoulder in secondary care: Developing and implementing stand-alone and post operative protocols for UK FROST and inferences for wider practice.

OBJECTIVES: The United Kingdom Frozen Shoulder Trial (UK FROST) compares stand-alone physiotherapy and two operative procedures, both with post operative rehabilitation, for primary frozen shoulder in secondary care. We developed physiotherapy protocols for UK FROST, incorporating best evidence but recognizing uncertainty and allowing flexibility. METHODS: We screened a UK Department of Health systematic review and UK evidence-based guidelines (Hanchard et al., 2012; Maund et al., 2012) for recommendations, and previous surveys of UK physiotherapists (Hanchard et al., 2011, 2013) for strong consensus. We conducted a two-stage, questionnaire-based, modified Delphi survey of shoulder specialist physiotherapists in the UK National Health Service. This required positive, negative or neutral ratings of possible interventions in four clinical contexts (stand-alone physiotherapy for, respectively, predominantly painful and predominantly stiff frozen shoulder; and post operative physiotherapy for, respectively, predominantly painful and predominantly stiff frozen shoulder). We proposed respectively mandating or recommending interventions with 100% and 90% positive consensus, and respectively disallowing or discouraging interventions with 90% and 80% negative consensus. Other interventions would be optional. RESULTS: The systematic review and guideline recommended including steroid injection and manual mobilizations in non-operative care, and we mandated these for stand-alone physiotherapy. Consensus in the pre-existing surveys strongly favoured advice, education and home exercises, which we mandated across contexts. The Delphi survey led to recommendation of some supervised exercise modalities, plus the disallowing or discouragement-in various contexts-of immobilization and some 'higher-tech' electrotherapies and alternative therapies. CONCLUSIONS: We developed physiotherapy protocols despite incomplete empirical evidence. Their clear structure enabled implementation in data-sheets designed to facilitate recording, monitoring of fidelity and reporting of interventions. Other trials involving physiotherapy may benefit from this approach.

The use of a patch to augment rotator cuff surgery - A survey of UK shoulder and elbow surgeons.

BACKGROUND: Rotator cuff tears are a common cause of shoulder pain and can result in prolonged periods of pain, disability and absence from work. Rotator cuff repair surgery is increasingly used in an attempt to resolve symptoms but has failure rates of around 40%. There is a pressing need to improve the outcome of rotator cuff repairs. Patch augmentation increasingly being used within the NHS in an attempt to reduce repair failures. The aim of this survey was to determine current UK practice and opinion relating to the factors that influence choice of patch, current patient selection and willingness to assist with generation of improved evidence. METHODS: An online survey was sent to the surgeon members of the British Elbow and Shoulder Society (BESS). Questions covered respondent demographics, experience with patches, indications for patch augmentation and willingness to be involved in a randomised trial of patch augmented rotator cuff surgery. RESULTS: The response rate was 105/550 (19%). 58% of respondents had used a patch to augment rotator cuff surgery. 70% of patch users had undertaken an augmented repair within the last 6 months. A wide surgical experience in augmentation was reported (ranging 1 to 200 implants used). However, most surgeons reported low volume usage, with a median of 5 rotator cuff augmentation procedures performed. At least 10 different products had been used. Most of the patches used were constructed from human decellularised dermis tissue, although porcine derived and synthetic based patches had also been used. Only 3-5% stated they would undertake an augmented repair for small tears across ages, whereas 28-40% and 19-59% would do so for large or massive tears respectively. When assessing patient suitability, patient age seemed relevant only for those with large and massive tears. Half of the surgeons reported an interest in taking part in a randomised controlled trial (RCT) evaluating the role of patch augmentation for rotator cuff surgery, with a further 22% of respondent's undecided. CONCLUSIONS: A variety of patches have been used by surgeons to augment rotator cuff repair with a wide range of operator experience. There was substantial uncertainty about which patch to use and differing views on which patients were most suitable. There is a clear need for robust clinical evaluation and further research in this area.

Percutaneous fixation with Kirschner wires versus volar locking-plate fixation in adults with dorsally displaced fracture of distal radius: five-year follow-up of a randomized controlled trial.

AIMS: The aim of this study was to compare the clinical effectiveness of Kirschner wire (K-wire) fixation with locking-plate fixation for patients with a dorsally displaced fracture of the distal radius in the five years after injury. PATIENTS AND METHODS: We report the five-year follow-up of a multicentre, two-arm, parallel-group randomized controlled trial. A total of 461 adults with a dorsally displaced fracture of the distal radius within 3 cm of the radiocarpal joint that required surgical fixation were recruited from 18 trauma centres in the United Kingdom. Patients were excluded if the surface of the wrist joint was so badly displaced it required open reduction. In all, 448 patients were randomized to receive either K-wire fixation or locking-plate fixation. In the K-wire group, there were 179 female and 38 male patients with a mean age of 59.1 years (19 to 89). In the locking-plate group, there were 194 female and 37 male patients with a mean age of 58.3 years (20 to 89). The primary outcome measure was the patient-rated wrist evaluation (PRWE). Secondary outcomes were health-related quality of life using the EuroQol five-dimension three-level (EQ-5D-3L) assessment, and further surgery related to the index fracture. RESULTS: At 12 months, 402/448 participants (90%) recruited into the main study provided PRWE scores. At year two, 294 participants (66%) provided scores; at year five, 198 participants (44%) provided scores. There was no clinically relevant difference in the PRWE at any point during the five-year follow-up; at five years, the PRWE score was 8.3 (12.5) in the wire group and 11.3 (15.6) in the plate group (95% confidence interval -6.99 to 0.99; p = 0.139). Nor was there a clinically relevant difference in health-related quality of life. Only three participants had further surgery in the five years after their injury (one in the wire group and two in the plate group). CONCLUSION: This follow-up study continues to show no evidence of a difference in wrist pain, wrist function, or quality of life for patients treated with wires versus locking plates in the five years following a dorsally displaced fracture of the distal radius.

Scoping review: Diagnosis and management of periprosthetic joint infection in elbow arthroplasty.

BACKGROUND: Total elbow arthroplasty is an effective treatment for patients with painful elbow arthritis. Infection can be a serious complication. The aim of this scoping review was to document the available evidence on periprosthetic elbow infection. METHODS: A search of Medline, Embase and PubMed was performed; two authors screened results independently. Systematic reviews, randomised controlled trials, cohort studies, case-control studies and case series including periprosthetic elbow infection were eligible. RESULTS: A total of 46 studies were included. The median rate of periprosthetic elbow infection reported from recent published studies is 3.3%. The most commonly identified causative organisms are Staphylococcus aureus and Staphylococcus epidermidis. Risk factors include younger age, rheumatoid arthritis, obesity, previous surgery or infection to the elbow, and postoperative wound complications. Debridement, antibiotics and implant retention results in implant survival rates of 50-90%. Two-stage revision results in improved functional outcome scores, but with recurrent infection rates of 12-28%. CONCLUSIONS: Total elbow arthroplasty carries a higher risk of infection when compared to other major joint replacements. The current body of literature is limited and is almost exclusively low volume retrospective case series. The best management of periprosthetic elbow infection is difficult to determine, but two-stage revision appears to be the gold standard.

Consumption of 'extra' foods by Australian children: types, quantities and contribution to energy and nutrient intakes.

OBJECTIVE: To measure the types and quantities of energy-dense, nutrient-poor 'extra' foods consumed by Australian children and adolescents and their contribution to total energy and nutrient intakes. DESIGN, SETTING AND SUBJECTS: We used data from 3007 children, aged 2-18 years, who participated in the nationally representative 1995 National Nutrition Survey. Intake was determined by 24-h recall and 'extra' foods were defined using principles outlined in the Australian Guide to Healthy Eating (AGHE) and by applying cut points for maximum amounts of fat and sugar within each food category. RESULTS: All children (99.8%) consumed at least one 'extra' food and the most commonly consumed were margarine, sugar-sweetened soft drinks, cordials and sugar. 'Extra' foods contributed 41% of daily energy intake. Those foods contributing most to energy intake were fried potatoes (4.2%), sugar-sweetened soft drinks (3.3%), ice cream/ice confection (3.1%) and cordials (2.7%). Age and sex were important determinants of 'extra' food intake, with males and older children generally consuming more and different types of, 'extra' foods than females and younger children. 'Extra' foods contributed 19% protein, 47% total fat, 47% saturated fat, 54% sugar, and approximately 20-25% of selected micronutrients to the diet. Calcium and zinc intakes from core foods were below 70% of the recommended dietary intakes for adolescent girls. CONCLUSIONS: 'Extra' foods are over-consumed at two to four times the recommended limits and contribute excessively to the energy, fat and sugar intakes of Australian children, while providing relatively few micronutrients. This is of concern in terms of children's weight and nutrient status.
