We designed and internally validated an aggregate weighted early warning scoring system specific to the obstetric population that has the potential for use in the ward environment. Direct obstetric admissions from the Intensive Care National Audit and Research Centre's Case Mix Programme Database were randomly allocated to model development (n = 2240) or validation (n = 2200) sets. Physiological variables collected during the first 24 h of critical care admission were analysed. Logistic regression analysis for mortality in the model development set was initially used to create a statistically based early warning score. The statistical score was then modified to create a clinically acceptable early warning score. Important features of this clinical obstetric early warning score are that the variables are weighted according to their statistical importance, a surrogate for the FIO2/P aO2 relationship is included, conscious level is assessed using a simplified alert/not alert variable, and the score, trigger thresholds and response are consistent with the new non-obstetric National Early Warning Score system. The statistical and clinical early warning scores were internally validated using the validation set. The area under the receiver operating characteristic curve was 0.995 (95% CI 0.992-0.998) for the statistical score and 0.957 (95% CI 0.923-0.991) for the clinical score. Pre-existing empirically designed early warning scores were also validated in the same way for comparison. The area under the receiver operating characteristic curve was 0.955 (95% CI 0.922-0.988) for Swanton et al.'s Modified Early Obstetric Warning System, 0.937 (95% CI 0.884-0.991) for the obstetric early warning score suggested in the 2003-2005 Report on Confidential Enquiries into Maternal Deaths in the UK, and 0.973 (95% CI 0.957-0.989) for the non-obstetric National Early Warning Score. This highlights that the new clinical obstetric early warning score has an excellent ability to discriminate survivors from non-survivors in this critical care data set. Further work is needed to validate our new clinical early warning score externally in the obstetric ward environment. © Anaesthesia © 2013 The Association of Anaesthetists of Great Britain and Ireland.

There has been extensive discussion about the effect of delay to surgery on mortality in patients sustaining a fracture of the hip. Despite the low level of evidence provided by many studies, a consensus has been accepted that delay of > 48 hours is detrimental to survival. The aim of this prospective observational study was to determine if early surgery confers a survival benefit at 30 days. Between 1989 and 2013, data were prospectively collected on patients sustaining a fracture of the hip at Peterborough City Hospital. They were divided into groups according to the time interval between admission and surgery. These thresholds ranged from < 6 hours to between 49 and 72 hours. The outcome which was assessed was the 30-day mortality. Adjustment for confounders was performed using multivariate binary logistic regression analysis. In all, 6638 patients aged > 60 years were included. Worsening American Society of Anaesthesiologists grade (p < 0.001), increased age (p < 0.001) and extracapsular fracture (p < 0.019) increased the risk of 30-day mortality. Increasing mobility score (p = 0.014), mini mental test score (p < 0.001) and female gender (p = 0.014) improved survival. After adjusting for these confounders, surgery before 12 hours improved survival compared with surgery after 12 hours (p = 0.013). Beyond this the increasing delay to surgery did not significantly affect the 30-day mortality. ©2015 The British Editorial Society of Bone & Joint Surgery.

An accurate characterization of nanomaterials used in clinical diagnosis and therapeutics is of paramount importance to realize the full potential of nanotechnology in medicine and to avoid unexpected and potentially harmful toxic effects due to these materials. A number of technical modalities are currently in use to study the physical, chemical and biological properties of nanomaterials but they all have advantages and disadvantages. In this review, we discuss the potential of a relative newcomer, tunable resistive pulse sensing, for the characterization of nanomaterials and its applications in nanodiagnostics. © 2016 Future Medicine Ltd.

In a randomised trial involving 598 patients with 600 trochanteric fractures of the hip, the fractures were treated with either a sliding hip screw (n = 300) or a Targon PF intramedullary nail (n = 300). The mean age of the patients was 82 years (26 to 104). All surviving patients were reviewed at one year with functional outcome assessed by a research nurse blinded to the treatment used. The intramedullary nail was found to have a slightly increased mean operative time (46 minutes (SD 12.3) versus 49 minutes (SD 12.7), p < 0.001) and an increased mean radiological screening time (0.3 minutes (SD 0.2) versus 0.5 minutes (SD 0.3), p < 0.001). Operative difficulties were more common with the intramedullary nail. There was no statistically significant difference between implants for wound healing complications (p = 1), or need for post-operative blood transfusion (p = 1), and medical complications were similarly distributed in both groups. There was a tendency to fewer revisions of fixation or conversion to an arthroplasty in the nail group, although the difference was not statistically significant (nine versus three cases, p = 0.14). The extent of shortening, loss of hip flexion, mortality and degree of residual pain were similar in both groups. The recovery of mobility was superior for those treated with the intramedullary nails (p = 0.01 at one year from injury). In summary, both implants produced comparable results but there was a tendency to better return of mobility for those treated with the intramedullary nail. ©2012 British Editorial Society of Bone and Joint Surgery.

Patients with unilateral vocal fold paralysis (UVFP) usually present with dysphonia, but can also be breathless and have problems with their swallowing. Speech and language therapy forms the initial mainstay of management in cases of UVFP, since up to 60% of cases will resolve spontaneously. If vocal fold paralysis persists surgery, in the form of injection medialisation, has been shown to be an effective intervention. What is currently unclear is which is the most effective material available for injection. To assess the effectiveness of alternative injection materials in the treatment of UVFP. We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; ICTRP and additional sources for published and unpublished trials. The date of the most recent search was 23 March 2012. Randomised controlled trials (RCTs) of injectable materials in patients with UVFP. The outcomes of interest were patient and clinician-reported improvement, and adverse events. Two authors independently selected studies from the search results and extracted data. We used the Cochrane 'Risk of bias' tool to assess study quality. We identified no RCTs which met the inclusion criteria for this review. We excluded 18 studies on methodological grounds: 16 non-randomised studies; one RCT due to inadequate randomisation and inclusion of non-UVFP patients; and one RCT which compared two different particle sizes of the same injectable material. There is currently insufficient high-quality evidence for, or against, specific injectable materials for patients with UVFP. Future RCTs should aim to provide a direct comparison of the alternative materials currently available for injection medialisation.

A total of 56 male patients with a displaced intracapsular fracture of the hip and a mean age of 81 years (62 to 94), were randomised to be treated with either a cemented hemiarthroplasty (the Exeter Trauma Stem) or reduction and internal fixation using the Targon Femoral Plate. All surviving patients were reviewed one year after the injury, at which time restoration of function and pain in the hip was assessed. There was no statistically significant difference in mortality between the two groups (7/26; 26.9% for hemiarthroplasty vs 10/30; 33.3% for internal fixation). No patient treated with a hemiarthroplasty required further surgery, but eight patients treated by internal fixation did (p = 0.005), five requiring hemiarthroplasty and three requiring total hip arthroplasty. Those treated by internal fixation had significantly more pain (p = 0.02). The restoration of mobility and independence were similar in the two groups. These results indicate that cemented hemiarthroplasty gives better results than internal fixation in elderly men with a displaced intracapsular fracture of the hip. © 2015 The British Editorial Society of Bone & Joint Surgery.

A consecutive series of 320 patients with an intracapsular fracture of the hip treated with a dynamic locking plate (Targon Femoral Neck (TFN)) were reviewed. All surviving patients were followed for a minimum of two years. During the follow-up period 109 patients died. There were 112 undisplaced fractures, of which three (2.7%) developed nonunion or redisplacement and five (4.5%) developed avascular necrosis of the femoral head. Revision to an arthroplasty was required for five patients (4.5%). A further six patients (5.4%) had elective removal of the plate and screws. There were 208 displaced fractures, of which 32 (15.4%) developed nonunion or redisplacement and 23 (11.1%) developed avascular necrosis. A further four patients (1.9%) developed a secondary fracture around the TFN. Revision to a hip replacement was required for 43 patients (20.7%) patients and a further seven (3.3%) had elective removal of the plate and screws. It is suggested that the stronger distal fixation combined with rotational stability may lead to a reduced incidence of complications related to the healing of the fracture when compared with other contemporary fixation devices but this needs to be confirmed in further studies. © 2013 The British Editorial Society of Bone & Joint Surgery.

We compared 5341 patients with an initial fracture of the hip with 633 patients who sustained a second fracture of the contralateral hip. Patients presenting with a second fracture were more likely to be institutionalised, female, older, and have lower mobility and mental test scores. There was no significant difference between the two groups with regards to the change in the level of mobility or return to their original residence at one year follow-up. However, the mortality rate in the second fracture group was significantly higher at one year (31.6% vs 27.3%, p = 0.024). In two thirds of patients, the second fracture was in the same anatomical location as the first. In an analysis of 293 patients, approximately 70% of second fractures occurred within three years of the first. This is the largest study to investigate the outcome of patients who sustain a second contralateral hip fracture. Despite the higher mortality rate at one year, the outcome for surviving patients is not significantly different from those after initial hip fractures. ©2012 British Editorial Society of Bone and Joint Surgery.

Whilst on operations, British military medical staff strive to provide high quality medical care to deployed soldiers. The application of UK Health Care Governance principles, particularly Clinical Professional Development (CPD), is especially challenging on operations. This article highlights some of the difficulties faced and the solutions generated to facilitate good CPD of Combat Medical Technicians (CMTs) deployed to Afghanistan on Operation HERRICK 13. The article describes the opportunities for CMTs to develop their skills in the assessment and management of trauma and primary health complaints. It also describes the difficulties in capturing this development especially when the supervision of CMTs was limited, with variable communication modalities and within the current limitations of the CMT portfolio. Solutions described include the use of individual reflective practice, face-to-face supervision and assessment by Medical Officers, Significant Event Reports, the mandatory After Action Review Process, and the development of formal standardised CMT CPD. This included refresher training after return from leave, Senior Medical Officer (SMO) weekly lectures and the SMO weekly report. Finally, the future of CMT CPD is raised and it is hoped that this article will stimulate debate into how to approach these challenges and refine these processes further.

Prospective data on 6905 consecutive hip fracture patients at a district general hospital were analysed to identify the risk factors for the development of deep infection post-operatively. The main outcome measure was infection beneath the fascia lata. A total of 50 patients (0.7%) had deep infection. Operations by consultants or a specialist hip fracture surgeon had half the rate of deep infection compared with junior grades (p = 0.01). Increased duration of anaesthesia was significantly associated with deep infection (p = 0.01). The method of fracture fixation was also significant. Intracapsular fractures treated with a hemiarthroplasty had seven times the rate of deep infection compared with those treated by internal fixation (p = 0.001). Extracapsular fractures treated with an extramedullary device had a deep infection rate of 0.78% compared with 0% for those treated with intramedullary devices (p = 0.02). The management of hip fracture patients by a specialist hip fracture surgeon using appropriate fixation could significantly reduce the rate of deep infection and associated morbidity, along with extended hospitalisation and associated costs. ©2012 British Editorial Society of Bone and Joint Surgery.
