Making an accurate diagnosis of anterior mediastinal lesions: a proposal for a new diagnostic algorithm from the BTOG Thymic Malignancies Special Interest Group.

Due to the rising demand in cross-sectional thoracic imaging, anterior mediastinal lesions are being identified with increasing frequency. Following iterative and multidisciplinary discussions, the BTOG Thymic Malignancies Special Interest Group have developed an algorithm to standardise the diagnostic approach for these relatively uncommon but important conditions which span from benign (thymic remnant, thymic hyperplasia and thymic cysts) to suspected localised thymomas to suspected more aggressive malignancy (thymic carcinoma, lymphoma and germ cell tumours). For each condition, we provide a brief description, an overview of the key radiological findings and a description of the proposed algorithm including the rationale behind the recommendations. We also highlight the role of magnetic resonance (MR) imaging for the characterisation of anterior mediastinal masses in specific indications when the necessary local resources and expertise exist. In addition, we hope this provides the rationale for service development in MR of the anterior mediastinum where current resource and expertise requires development. Through this standardised pathway, we hope to drive improvements in patient care by rationalising surveillance schedules, avoiding unnecessary resections of benign entities with their associated morbidity and optimising the diagnostic work-up prior to the appropriate treatment of anterior mediastinal malignancies.

Immune modulation via dendritic cells by the effect of Thymosin-alpha-1 on immune synapse in HCMV infection.

Tα1 (Thymosin-alpha-1) is a thymus-derived hormone that has been demonstrated to be effective on diverse immune cell subsets. The objective of this study was to determine the in vitro immunomodulatory effect of Tα1 in human cytomegalovirus (HCMV) infection. Dendritic cells (DCs) were isolated from peripheral blood mononuclear cells (PBMCs) by negative selection and cultured in the presence or absence of Tα1. The immunophenotyping of DCs was characterised by multiparametric flow cytometry assessing CD40, CD80, TIM-3 and PDL-1 markers, as well as intracellular TNFα production. Then, autologous CD4+ or CD8+ T-Lymphocytes (TLs) isolated by negative selection from PBMCs were co-cultured with DCs previously treated with Tα1 in the presence or absence of HCMV. Intracellular TNFα, IFNγ, IL-2 production, CD40-L and PD-1 expression were assessed through immunophenotyping, and polyfunctionality in total TLs and memory subsets were evaluated. The results showed that Tα1 increased CD40, CD80, TIM-3 and TNFα intracellular production while decreasing PDL-1 expression, particularly on plasmacytoid dendritic cells (pDCs). Therefore, Tα1 modulated the production of TNFα, IFNγ and IL-2 in both total and memory subsets of CD4+ and CD8+ TLs by upregulating CD40/CD40-L and downregulating PDL-1/PD-1 expression. Our study concludes that Tα1 enhances antigen-presenting capacity of DCs, improves TLs responses to HCMV infection, and enhances the polyfunctionality of CD8+ TLs. Consequently, Tα1 could be an alternative adjuvant for use in therapeutic cell therapy for immunocompromised patients.

[Recommendations for thromboembolic disease in oncological processes. A view from primary care]. / Recomendaciones sobre enfermedad tromboembólica venosa en procesos oncológicos. Una visión desde la medicina de familia.

Venous thromboembolic disease (VTE) is a frequent complication in patients diagnosed with cancer and a cause of morbidity and mortality. Approximately 20% of thromboembolic episodes develop in association with active cancer. On the other hand, it is estimated that about 2-12% of cases, the thromboembolic episode is the first manifestation of an occult cancer, diagnosed at that time or subsequently, which offers an opportunity for early diagnosis and treatment. There are multiple factors that contribute to increase the risk of VTE in oncological patients in relation to specific characteristics of the patient, the tumor and the treatments. Knowledge of these risk factors will contribute to early diagnosis when signs of VTE appear, as well as the assessment of thromboprophylaxis if indicated. The diagnosis of VTE in patients with cancer does not differ of those who do not suffer from it. Regarding the treatment of VTE in these patients, low molecular weight heparin (LMWH), direct acting anticoagulants (DACs) and antivitamin K (VKA) are the most commonly used, although the dosing regimen and length are not clear yet. The management of these patients should be interdisciplinary and early, so the primary care physician plays a key role in this process as he/she is liaise with his/her patients. It is also necessary to update knowledge in order to improve the care of these patients. For these reasons, this document has been prepared by the Working Group on Vasculopathies of the Spanish Society of Primary Care Physicians (SEMERGEN) whose objective is to present the available information regarding the management of VTE that may appear in oncological patients, as well as the assessment of thromboprophylaxis and treatment, if appropriate, from an approach focused on a primary care field.

Cardiovascular diseases among diffuse large B-cell lymphoma long-term survivors in Asia: a multistate model study.

BACKGROUND: We modeled the clinical course of a cohort of diffuse large B-cell lymphoma (DLBCL) patients with no prior cardiovascular diseases (CVDs) using a multistate modeling framework. PATIENTS AND METHODS: Data on 2600 patients with DLBCL diagnosed between 2000 and 2018 and had received chemotherapy with or without radiotherapy were obtained from a population-wide electronic health database of Hong Kong. We used the Markov illness-death model to quantify the impact of doxorubicin and various risk factors (therapeutic exposure, demographic, comorbidities, cardiovascular risk factors, and lifestyle factors which included smoking) on the clinical course of DLBCL (transitions into incident CVD, lymphoma death, and other causes of death). RESULTS: A total of 613 (23.6%) and 230 (8.8%) of 2600 subjects died of lymphoma and developed incident CVD, respectively. Median follow-up was 7.0 years (interquartile range 3.8-10.8 years). Older ages [hazard ratio (HR) for >75 versus ≤60 years 1.88; 95% confidence interval (CI) 1.25-2.82 and HR for 61-75 versus ≤60 years 1.60; 95% CI 1.12-2.30], hypertension (HR 4.92; 95% CI 2.61-9.26), diabetes (HR 1.43; 95% CI 1.09-1.87), and baseline use of aspirin (HR 5.30; 95% CI 3.93-7.16) were associated with an increased risk of incident CVD. In a subgroup of anticipated higher-risk patients (aged 61-75 years, smoked, had diabetes, and received doxorubicin), we found that they remained on average 7.9 (95% CI 7.2-8.8) years in the DLBCL state and 0.1 (95% CI 0.0-0.4) years in the CVD state, if they could be followed up for 10 years. The brief time in the CVD state is consistent with the high chance of death in patients who developed CVD. Other causes of death have overtaken DLBCL-related death after about 5 years. CONCLUSIONS: In this Asian population-based cohort, we found that incident CVDs can occur soon after DLBCL treatment and continued to occur throughout survivorship. Clinicians are advised to balance the risks and benefits of treatment choices to minimize the risk of CVD.

Idiopathic granulomatous mastitis after ductoscopy: A case report.

INTRODUCTION AND IMPORTANCE: Idiopathic granulomatous mastitis (IGM) is an uncommon, benign, chronic inflammatory breast disease of unknown etiology, unpredictable duration, and unclear therapy. PRESENTATION OF CASE: A 41-year-old woman presented with pathological nipple discharge for which ductoscopy was performed. Post-ductoscopy, the patient developed abscesses in her breast with histopathological confirmation of granulomatous mastitis (GM). CLINICAL DISCUSSION AND CONCLUSION: IGM has an unknown etiology and atypical presentation. This is the only case described in which IGM occurred after ductoscopy. This can be related to trauma-induced GM or underlying IGM aggravated by ductoscopy.

[Shock wave treatment in a case of complicated plantaris muscle rupture]. / Tratamiento con ondas de choque en un caso de rotura muscular del delgado plantar complicada.

Muscle injuries are frequent in the workplace. They are produced by sudden direct or indirect trauma that involves a rupture of the fibres, causing bruising. Currently, there is no single protocol-based model of treatment. We present the case of a patient diagnosed with complete muscular rupture of the plantaris muscle by an indirect traumatic mechanism (abrupt muscular elongation), with an associated large-volume hematoma. Clinical study consisted of ultrasound, magnetic resonance (MR), pain assessment (VAS) at the beginning and at the end of the treatment (3 weeks), as well as duration of occupational disability. The patient underwent extracorporeal shockwave therapy (ESWT) according to the protocol. At the end of treatment, the hematoma was resolved and there were no complications. ESWT could be a complementary therapeutic alternative to conventional treatment in this entity. However, there is a need for further, randomised controlled studies including a larger number of patients.

Patient, tumor, and healthcare factors associated with regional variability in lung cancer survival: a Spanish high-resolution population-based study.

PURPOSE: The third most frequently diagnosed cancer in Europe in 2018 was lung cancer; it is also the leading cause of cancer death in Europe. We studied patient and tumor characteristics, and patterns of healthcare provision explaining regional variability in lung cancer survival in southern Spain. METHODS: A population-based cohort study included all 1196 incident first invasive primary lung cancer (C33-C34 according to ICD-10) cases diagnosed between 2010 and 2011 with follow-up until April 2015. Data were drawn from local population-based cancer registries and patients' hospital medical records from all public and private hospitals from two regions in southern Spain. RESULTS: There was evidence of regional differences in lung cancer late diagnosis (58% stage IV in Granada vs. 65% in Huelva, p value < 0.001). Among patients with stage I, only 67% received surgery compared with 0.6% of patients with stage IV. Patients treated with a combination of radiotherapy, chemotherapy, and surgery had a 2-year mortality risk reduction of 94% compared with patients who did not receive any treatment (excess mortality risk 0.06; 95% CI 0.02-0.16). Geographical differences in survival were observed between the two regions: 35% vs. 26% at 1-year since diagnosis. CONCLUSIONS: The observed geographic differences in survival between regions are due in part to the late cancer diagnosis which determines the use of less effective therapeutic options. Results from our study justify the need for promoting lung cancer early detection strategies and the harmonization of the best practice in lung cancer management and treatment.

Persistent inequalities in 90-day colon cancer mortality: an English cohort study.

BACKGROUND: Variation in colon cancer mortality occurring shortly after diagnosis is widely reported between socio-economic status (SES) groups: we investigated the role of different prognostic factors in explaining variation in 90-day mortality. METHODS: National cancer registry data were linked with national clinical audit data and Hospital Episode Statistics records for 69 769 adults diagnosed with colon cancer in England between January 2010 and March 2013. By gender, logistic regression was used to estimate the effects of SES, age and stage at diagnosis, comorbidity and surgical treatment on probability of death within 90 days from diagnosis. Multiple imputations accounted for missing stage. We predicted conditional probabilities by prognostic factor patterns and estimated the effect of SES (deprivation) from the difference between deprivation-specific average predicted probabilities. RESULTS: Ninety-day probability of death rose with increasing deprivation, even after accounting for the main prognostic factors. When setting the deprivation level to the least deprived group for all patients and keeping all other prognostic factors as observed, the differences between deprivation-specific averaged predicted probabilities of death were greatly reduced but persisted. Additional analysis suggested stage and treatment as potential contributors towards some of these inequalities. CONCLUSIONS: Further examination of delayed diagnosis, access to treatment and post-operative care by deprivation group may provide additional insights into understanding deprivation disparities in mortality.

Ceramic-on-ceramic bearing fractures in total hip arthroplasty: an analysis of data from the National Joint Registry.

AIMS: Ceramic-on-ceramic (CoC) bearings in total hip arthroplasty (THA) are commonly used, but concerns exist regarding ceramic fracture. This study aims to report the risk of revision for fracture of modern CoC bearings and identify factors that might influence this risk, using data from the National Joint Registry (NJR) for England, Wales, Northern Ireland and the Isle of Man. PATIENTS AND METHODS: We analysed data on 223 362 bearings from 111 681 primary CoC THAs and 182 linked revisions for bearing fracture recorded in the NJR. We used implant codes to identify ceramic bearing composition and generated Kaplan-Meier estimates for implant survivorship. Logistic regression analyses were performed for implant size and patient specific variables to determine any associated risks for revision. RESULTS: A total of 222 852 bearings (99.8%) were CeramTec Biolox products. Revisions for fracture were linked to seven of 79 442 (0.009%) Biolox Delta heads, 38 of 31 982 (0.119%) Biolox Forte heads, 101 of 80 170 (0.126%) Biolox Delta liners and 35 of 31 258 (0.112%) Biolox Forte liners. Regression analysis of implant size revealed smaller heads had significantly higher odds of fracture (chi-squared 68.0, p < 0.001). The highest fracture risk was observed in the 28 mm Biolox Forte subgroup (0.382%). There were no fractures in the 40 mm head group for either ceramic type. Liner thickness was not predictive of fracture (p = 0.67). Body mass index (BMI) was independently associated with revision for both head fractures (odds ratio (OR) 1.09 per unit increase, p = 0.031) and liner fractures (OR 1.06 per unit increase, p = 0.006). CONCLUSIONS: We report the largest independent study of CoC bearing fractures to date. The risk of revision for CoC bearing fracture is very low but previous studies have underestimated this risk. There is good evidence that the latest generation of ceramic has greatly reduced the odds of head fracture but not of liner fracture. Small head size and high patient BMI are associated with an increased risk of ceramic bearing fracture. Cite this article: Bone Joint J 2017;99-B:1012-19.

The tip-apex distance in the X-Bolt dynamic plating system.

OBJECTIVES: The Sliding Hip Screw (SHS) is commonly used to treat trochanteric hip fractures. Fixation failure is a devastating complication requiring complex revision surgery. One mode of fixation failure is lag screw cut-out which is greatest in unstable fracture patterns and when the tip-apex distance of the lag screw is > 25 mm. The X-Bolt Dynamic Hip Plating System (X-Bolt Orthopaedics, Dublin, Ireland) is a new device which aims to reduce this risk of cut-out. However, some surgeons have reported difficulty minimising the tip-apex distance with subsequent concerns that this may lead to an increased risk of cut-out. PATIENTS AND METHODS: We measured the tip-apex distance from the intra-operative radiographs of 93 unstable trochanteric hip fractures enrolled in a randomised controlled trial (Warwick Hip Trauma Evaluation, WHiTE One trial). Participants were treated with either the sliding hip screw or the X-Bolt dynamic hip plating system. We also recorded the incidence of cut-out in both groups, at a median follow-up time of 17 months. RESULTS: There was a significantly increased tip-apex distance with the use of the X-Bolt (mean difference 3.7mm (95% confidence interval 1.58 to 5.73); SHS mean 17.1 mm, X-Bolt mean 20.8; p = 0.001. However, this was not associated with an increased incidence of cut-out at a median follow-up time of 17 months, with three cut-outs (6%) in the SHS group and 0 (0%) in the X-Bolt group. CONCLUSION: The X-Bolt is a safe implant with no increased risk for cut-out. Concerns about minimising the tip-apex distance may be justified but do not appear to be clinically important.Cite this article: M. A. Fernandez, A. Aquilina, J. Achten, N. Parsons, M. L. Costa, X.

Yogurt, diet quality and lifestyle factors.

Yogurt consumption has been associated with healthy dietary patterns and lifestyles, better diet quality and healthier metabolic profiles. Studies have shown that frequent yogurt consumers do not only have higher nutrient intakes, but also an improved diet quality, which includes higher consumption of fruits and vegetables, whole grains, and dairy compared with low or non-consumers indicating better compliance with dietary guidelines. Recent epidemiological and clinical evidence suggests that yogurt contributes to better metabolic health because of its effects on the control of body weight, energy homeostasis and glycemic control. Furthermore, yogurt consumers have been shown to be more physically active (⩾ 2 h/week), smoke less, have higher education and knowledge of nutrition compared with non-consumers. Thus, yogurt consumption may be considered a signature of a healthy diet through its nutritional content, impact on metabolic health including the control of energy balance, body weight and glycemia and its relationships with healthier behaviors and lifestyle factors.

Validation of the HIV Tropism Test TROCAI Using the Virological Response to a Short-Term Maraviroc Monotherapy Exposure.

TROCAI is a phenotypic tropism test developed using the virological response to a short-term exposure to maraviroc monotherapy (Maraviroc Clinical Test [MCT]). It was found that with TROCAI, a cutoff of <0.5% of dual/mixed viruses was needed to predict R5 HIV tropism. Here, we have validated TROCAI, using this cutoff, in a new cohort of 42 patients, finding a very high concordance between TROCAI and MCT (98%), and a good concordance (71 to 87%) with other genotypic/phenotypic methods.

Ability of HMGB1 protein to bind to intrinsically bent and non-bent DNA sites in the AMPD2 gene amplicon.

HMGB-like proteins are architectural chromatin factors, and their function is heavily dependent on their ability to interact with DNA (especially non-canonical DNA structures). HMGB1 is involved in many DNA processes, and dysregulation of HMGB protein expression has profound effects on cellular transcription, resulting in severe developmental defects as well as cancer. During DNA replication, elements that form the origin are still not well defined in metazoans. Sites with A (adenine) or T (thymine) repeats cause intrinsic curvatures in the DNA and are described to be involved in the replication machinery by providing binding sites to replication proteins. As a result, the DNA molecule shows intrinsically bent DNA sites, caused by periodic repeats of 2 or more As/Ts (dA/dT) as well as intrinsically non-bent DNA sites (INBDs), due to a succession of curvatures that cancel each other. In the present study, we mapped 11 INBDSs present in the AMPD2 gene that are related to each replication origin (oriGNAI3, oriC, oriB, and oriA). Following characterization of INBDSs, we tested the ability of HMGB1 to bind to the bent (b1, b2, b4a, b4b, b5, b6, b7, and b8) and non-bent DNA fragments (nb7, nb11, nb1, nb2, nb4, and nb5) via electrophoretic mobility shift assays. All fragments showed efficient binding to HMGB1. However, the non-bent DNA fragments nb2, nb4, and nb5 showed slightly reduced binding efficiency.

[Not Available]. / Efectividad de un programa de educación e intervención nutricional y de actividad física sobre la salud integral de mujeres posmenopáusicas.

Objetivos: el objetivo de este estudio fue comprobar la eficacia de un programa de educación e intervención nutricional, de salud integral y ejercicio físico en mujeres posmenopáusicas, incidiendo especialmente en el sector de mujeres fumadoras con el fin de reducir el riesgo cardiovascular de este sector de población. Materiales y métodos: la población objeto de estudio estuvo constituida por 96 mujeres (46-79 años) residentes en Granada (sur de España).Al comienzo del estudio se recogieron las características sociodemográficas y se realizó una valoración nutricional; el consumo de alimentos se evaluó mediante una encuesta de 48 preguntas y un estudio de adhesión a la dieta mediterránea. Se determinaron datos antropométricos: índice de masa corporal, porcentaje de masa grasa y magra. Determinamos también el colesterol total, el colesterol LDL, HDL y los triglicéridos.Una vez obtenidos los primeros resultados, se realizó una intervención personalizada, para cada mujer participante en el estudio, de educación nutricional y de hábitos saludables. Transcurridos tres meses, se volvieron a determinar todos los parámetros anteriormente estudiados. Resultados: al comienzo del estudio se observó que la dieta de la población se adecuaba a los patrones de dieta saludable y tras la intervención nutricional se produjo una mejora del perfil calórico y lipídico y un descenso de la obesidad. En el grupo de las mujeres fumadoras además se encontró una mejora de los parámetros lipídicos séricos, alcanzando valores semejantes a los de las no fumadoras. Conclusiones: se observó que las mujeres posmenopáusicas andaluzas participantes en este estudio tenían una adecuada adhesión a la dieta mediterránea. La intervención nutricional mejoró en todo el grupo la calidad de la dieta y el porcentaje de obesidad y, además en las mujeres fumadoras mejoró el perfil lipídico.

Phenotype and Polyfunctional Deregulation Involving Interleukin 6 (IL-6)- and IL-10-Producing Monocytes in HIV-Infected Patients Receiving Combination Antiretroviral Therapy Differ From Those in Healthy Older Individuals.

BACKGROUND: Despite the relevance of monocytes as promoters of the inflammatory response, whether human immunodeficiency virus (HIV) infection induces premature age-related changes to the phenotype and function of monocytes or whether these alterations are different and/or specifically driven by HIV remains to be mechanistically determined. METHODS: We assayed the activation phenotype and the responsiveness in vitro to Toll-like receptor (TLR) agonists in classical, intermediate, and nonclassical subsets of monocytes by assessing intracellular interleukin 1α (IL-1α), IL-1ß, interleukin 6 (IL-6), interleukin 8, tumor necrosis factor α, and interleukin 10 (IL-10) production in 20 HIV-infected patients receiving combination antiretroviral therapy (cART) and 2 groups of uninfected controls (20 age-matched young individuals and 20 older individuals aged >65 years). RESULTS: HIV-infected patients showed a more activated phenotype of monocytes than older controls. Regarding functionality, under unstimulated conditions HIV-infected patients showed a higher percentage of classical monocytes producing IL-6 and IL-10 than control subjects. The percentage of cells with production of multiple cytokines (polyfunctionality), including IL-10, in response to TLR agonists was greater among HIV-infected patients than among control subjects. CONCLUSIONS: Inflammatory alterations associated with monocytes during HIV infection are different from those in aging individuals. This monocyte dysfunction, mainly characterized by high levels of IL-6- and IL-10-producing monocytes, may have clinical implications in HIV-infected patients that are different from those in aging individuals.

Contribution of JAK2 mutations to T-cell lymphoblastic lymphoma development.

The JAK-STAT pathway has a substantial role in lymphoid precursor cell proliferation, survival and differentiation. Nonetheless, the contribution of JAK2 to T-cell lymphoblastic lymphoma (T-LBL) development remains poorly understood. We have identified one activating TEL-JAK2 translocation and four missense mutations accumulated in 2 out of 16 T-LBL samples. Two of them are novel JAK2 mutations and the other two are reported for the first time in T-LBL. Notably, R683G and I682T might have arisen owing to RNA editing. Mutated samples showed different mutated transcripts suggesting sub-clonal heterogeneity. Functional approaches revealed that two JAK2 mutations (H574R and R683G) constitutively activate JAK-STAT signaling in γ2A cells and can drive the proliferation of BaF3-EpoR cytokine-dependent cell line. In addition, aberrant hypermethylation of SOCS3 might contribute to enhance the activation of JAK-STAT signaling. Of utmost interest is that primary T-LBL samples harboring JAK2 mutations exhibited increased expression of LMO2, suggesting a mechanistic link between JAK2 mutations and the expression of LMO2, which was confirmed for the four missense mutations in transfected γ2A cells. We therefore propose that active JAK2 contribute to T-LBL development by two different mechanisms, and that the use of pan-JAK inhibitors in combination with epigenetic drugs should be considered in future treatments.

[Cervical thymic cyst in childhood]. / Quiste tímico cervical en la infancia.

Cervical thymus cyst is a rare cause of neck mass in children. . Approximately 90 cases have been described, and just a few have been published in Spanish literature. They usually appear in early children and are diagnosed as brachial cyst. We report the case of a 6 year old boy with a swelling on the right side of the neck. The swelling had appeared a few months before. Ultrasound examination of a neck mass and MRI showed a cystic mass compatible with possible branchial cyst. Excision of the tumor was performed. Pathology showed cystic mass with remains of thymic tissue in the walls, so the final diagnosis was cervical thymic cyst.

El quiste tímico cervical es una causa infrecuente de masa cervical en la infancia. Se han descrito unos 90 casos y pocos han sido publicados en la literatura española. Normalmente aparecen en la primera infancia y se diagnostican como quiste branquial. Presentamos el caso de un niño de 6 años de edad sin antecedentes patológicos de interés, que consulta por tumoración laterocervical derecha de 3 meses de evolución. Los estudios con ecografía cervical y resonancia nuclear magnética muestran una masa de aspecto quístico compatible con posible quiste branquial. Se realiza exéresis de la tumoración. El estudio anatomopatológico evidenció que se trataba de una masa quística con restos de tejido tímico en sus paredes, por lo que el diagnóstico final fue de quiste tímico cervical.

The impact of a dedicated orthoplastic operating list on time to soft tissue coverage of open lower limb fractures.

An observational study was conducted of 105 patients presenting with an open fracture of the tibia or ankle to determine the impact of a dedicated orthoplastic operating list on our management of these injuries over the time period January 2012 to July 2014. There were 51 patients before and 54 after the introduction of the orthoplastic list. Significant improvements were noted in our ability to deliver a service in line with national guidelines across all Gustilo-Anderson grades of injury. Among patients with the most severe grades of injury (Gustilo types IIIB and IIIC), there was a trend towards an improved time to first skeletal stabilisation (29.5 vs 14.2 hours, p=0.068), an improvement in time to soft tissue coverage (173.6 vs 88.1 hours, p=0.009) and a trend towards a reduced length of inpatient stay (32.6 vs 23.2 days, p=0.138). Where the 72-hour target had been breached, there was a significant improvement in the proportion of patients covered within 7 days of injury (48.2% vs 83.3%, p=0.017). Our compliance with national management standards increased significantly to reflect these improvements in care. These results support the implementation of dedicated orthoplastic operating sessions to meet the growing burden of patients presenting with open fractures at specialist centres.

Management of hip fracture.

INTRODUCTION: Hip fracture poses a significant global challenge both to healthcare systems and to patients themselves. We outline the management of this injury, highlight areas where the evidence is deficient and discuss research efforts towards improving the quality of the evidence base. SOURCES OF DATA: We searched MEDLINE, PubMed and the Cochrane Library, using the core search terms 'hip fracture' and 'proximal femoral fracture'. In addition we reviewed national treatment guidelines for hip fracture care and references from relevant articles. Only articles published in English from inception to March 2015 were included. AREAS OF AGREEMENT: Modern hip fracture management should consist of a coordinated multidisciplinary approach with orthogeriatrician input, early surgery, adequate analgesia and liaison with related services to facilitate safe supported discharge. AREAS OF CONTROVERSY: The optimum thromboprophylaxis to reduce venous thromboembolism remains a topic for debate. The use of bone cement has received much attention recently with concerns about its safety in the frailest of hip fracture patients. GROWING POINTS: An increasing understanding of the severity and impact of sustaining a hip fracture upon quality of life. AREAS TIMELY FOR DEVELOPING RESEARCH: Strategies to improve postoperative mobility, postoperative nutrition and the role of home-based rehabilitation. There is a need to identify the optimum analgesic regimes and assessment tools for hip fracture patients with cognitive impairment.
