Abstract:

ObjectiveSince 2014 Senegal has benefited from regular awareness-raising Short Message Service (SMS) campaigns (Be He@lthy, Be Mobile initiative) directed at people who have signed up, for free, to the ‘mDiabète’ programme. We report on an evaluation of its impact on diabetes control.DesignThe clinical trial was designed to send daily SMS during 3 months to people with type 2 diabetes. Due to centre randomisation, SMS were sent from inclusion (M0) to month 3 (M3) to people in centre S and from M3 to month 6 (M6) to people in centre P.SettingMedical centre S in the northwestern suburbs of Dakar; centre P in Popenguine, 70 km south of Dakar.ParticipantsIn February 2017, people with type 2 diabetes were consecutively recruited in the two centres. Complete data were available from 186 of these people.Main outcome measuresHbA1c was measured in the two centres with the same assay throughout the study. The primary end point was the difference between centres for the change in HbA1c from M0 to M3. Secondary end points were the evolution of HbA1c in centres S and P between M3 and M6.ResultsThe HbA1c change from M0 to M3 in centre S was better than in centre P, with a median difference of −0.4%, quartiles (−1.0; 0.3) versus 0.2% (-0.5; 0.8), respectively (p=0.0038). HbA1c decreased over the 3 months after having stopped SMS in centre S and was confirmed in centre P. The campaign cost was €2.5 (US$3.1) per person.ConclusionsIn Senegal, SMS sending was associated with an improved glycaemic control in people with type 2 diabetes. As SMS has a high penetration in low-income, middle-income countries where medical resources are scarce, health interventions using mobile telephones should be developed to facilitate exchanges between people with diabetes and medical teams; this may reduce diabetes-related complications.

Abstract:

IntroductionSevere aortic stenosis is a major cause of morbidity and mortality. The existing treatment pathway for transcatheter aortic valve implantation (TAVI) traditionally relies on tertiary Heart Valve Centre workup. However, this has been associated with delays to treatment, in breach of British Cardiovascular Intervention Society targets. A novel pathway with emphasis on comprehensive patient workup at a local centre, alongside close collaboration with a Heart Valve Centre, may help reduce the time to TAVI.MethodsThe centre performing local workup implemented a novel TAVI referral pathway. Data were collected retrospectively for all outpatients referred for consideration of TAVI to a Heart Valve Centre from November 2020 to November 2021. The main outcome of time to TAVI was calculated as the time from Heart Valve Centre referral to TAVI, or alternative intervention, expressed in days. For the centre performing local workup, referral was defined as the date of multidisciplinary team discussion. For this centre, a total pathway time from echocardiographic diagnosis to TAVI was also evaluated. A secondary outcome of the proportion of referrals proceeding to TAVI at the Heart Valve Centre was analysed.ResultsMean±SD time from referral to TAVI was significantly lower at the centre performing local workup, when compared with centres with traditional referral pathways (32.4±64 to 126±257 days, p<0.00001). The total pathway time from echocardiographic diagnosis to TAVI for the centre performing local workup was 89.9±67.6 days, which was also significantly shorter than referral to TAVI time from all other centres (p<0.003). Centres without local workup had a significantly lower percentage of patients accepted for TAVI (49.5% vs 97.8%, p<0.00001).DiscussionA novel TAVI pathway with emphasis on local workup within a non-surgical centre significantly reduced both the time to TAVI and rejection rates from a Heart Valve Centre. If adopted across the other centres, this approach may help improve access to TAVI.

Abstract:

Background: Ventriculoperitoneal (VP) shunts are an established treatment modality for CSF diversion. An alternative to VP shunting is lumboperitoneal (LP) shunting. There is a paucity of evidence on LP shunt use in the literature, but available studies demonstrate that it is a safer and similarly efficacious method for conditions such as normal pressure hydrocephalies (NPH) and idiopathic -intracranial hypertension (IIH). Methods: Ventriculoperitoneal (VP) shunts are an established treatment modality for CSF diversion. An alternative to VP shunting is lumboperitoneal (LP) shunting. There is a paucity of evidence on LP shunt use, but available studies demonstrate that it is a safer and similarly efficacious method for conditions such as normal pressure hydrocephalies (NPH) and idiopathic intracranial hypertension (IIH). Results: 95 patients were treated with lumboperitoneal shunt, 71 of which were for hydrocephalus and 24 for IIH. 39 male and 58 female patients were included with mean age 55 (range from 20 to 96 years old). 26 patients had laparoscopic placement of the peritoneal catheter. Mechanical issues with distal end was less with laparoscopic approach. Conclusions: We will review disease-specific scores for NPH and IIH, and compare laparoscopic with non-laparoscopic placement of peritoneal catheter. We will also compare outcomes and complications with rates for VP shunting.

Abstract:

AbstractA group G is said to be conjugacy p-separable if two non-conjugate elements of G remain non-conjugate in some finite p-group endomorphic image of G. We show that the non-cyclic free centre-by-metabelian groups are not conjugacy p-separable for any prime p. On the other hand, we show that every free centre-by-metabelian group has the solvable conjugacy problem

Abstract:

6625 Background: A recent study suggested that cardiotoxicity from trastuzumab (T) was associated with regional variation and insufficient cardiac monitoring (Ng et al.SABCS 2012). Few studies have examined the impact of centre or physician (MD) case volume (vol) on outcomes in systemic therapy. Methods: All breast cancer patients who were diagnosed in 2003-2009 in Ontario and treated with adjuvant T were identified through a provincial drug funding program, and linked to administrative databases to ascertain patient demographics, hospitalizations, cardiac risk factors, cardiac imaging, comorbidities, and treating centre and MD. For each year, we calculated case vol as the number of patients treated with adjuvant T by each MD and by each centre. Cardiotoxicity was defined as receiving less than 16 out of 18 doses of T because of heart failure (HF) admission, HF diagnosis by physician claims, or discontinuation after cardiac imaging. Insufficient cardiac monitoring was defined as per recent guideline and per Ng et al. Logistic regression and mixed models were constructed to examine factors associated with cardiotoxicity. Results: Our cohort consisted of 3,777 patients, 214 MDs and 68 centres. For patients, 16.5% were over age 65; 30.3%, 9.4%, and 1.2% had previous diagnoses of hypertension, diabetes, and HF, respectively; 16.9% had cardiotoxicity. Univariate analyses found that high centre vol, but not MD vol, was associated with lower cardiotoxicity. Cardiotoxicity rates by centre vol quintiles (Q) were 23.4% (Q1-3), 18.2% (Q4), and 15.2% (Q5). Multivariable analyses found that lower cardiotoxicity was associated with higher centre vol (OR=0.85 per Q, p=0.02) and diagnosis in recent years (2008-2009 vs. before 2008; OR=0.50, p<0.001), after adjusting for age, previous HF, comorbidities, regional variation, and cardiac monitoring. Accounting for clustering within centres, there remained a strong trend of lower cardiotoxicity with higher centre vol (OR=0.77 per Q, p=0.06) and recent diagnosis (OR=0.50, p<0.001). Conclusions: Our findings suggest a reduction in cardiotoxicity with experience and over time, and support the notion of centralization of systemic therapy in high vol centres to optimize outcomes.

Abstract:

ObjectiveTo evaluate the impact of immunisation service integration to nutrition programmes and under 5-year-old paediatric outpatient departments of primary healthcare centres in Rumbek East and Rumbek Centre counties of South Sudan.DesignRetrospective intervention study.SettingThree primary healthcare centres in Rumbek East county and three primary healthcare centres in Rumbek Centre county of Lakes state in South Sudan.ParticipantWe extracted the data for the uptake of pentavalent vaccine (first, second and third dose) given to children aged between 6 weeks and 23 months from immunisation records for January–June 2019 before immunisation service integration and July–December 2019 after immunisation service integration from the District Health Information System 2 website to estimate the immunisation uptake ratios and drop-out rates.ResultsThe uptake of the first dose of the pentavalent vaccine improved from 61% to 96% (p<0.001) after immunisation service integration into the nutrition programmes of the primary healthcare centres in Rumbek Centre county. The uptake of the second pentavalent dose improved from 37% to 69% (p<0.001) and for the third pentavalent dose from 36% to 62% (p<0.001), while the drop-out rate reduced from 57% to 40% (p<0.001). While in Rumbek East county, the uptake of the first dose of the pentavalent vaccine improved from 55% to 77% (p<0.001) after immunisation service integration into the under 5-year-old paediatric outpatient departments. The uptake of the second dose improved from 36% to 62% (p<0.001) and for the third dose from 44% to 63% (p<0.001), while the drop-out rate reduced from 40% to 28% (p<0.001). Children were 23% more likely (RR 1.23, 95% CI 1.12 to 1.36, p<0.001) to be immunised with the first dose of the pentavalent vaccine on immunisation service integration into the nutrition programmes of primary healthcare centres of Rumbek Centre county in comparison to integration into under 5-year-old outpatient departments of Rumbek East county.ConclusionIntegration of immunisation service delivery to nutrition sites and children’s outpatient departments improved the immunisation coverage and decreased drop-out rates in the Rumbek East and Rumbek Centre counties of South Sudan. This evidence of positive impact should encourage the stakeholders of the Expanded Programme on Immunisation to focus on the sustainability and scale-up of this intervention to other counties in South Sudan, as logistically as possible.

Abstract:

The association between healthy eating practices and child dietary intake in childcare centres where parents pack foods from home has received little attention. This study aimed to: (1) Describe the nutritional content of foods and beverages consumed by children in care; and (2) Assess the association between centre healthy eating practices and child intake of fruit and vegetable servings, added sugar(grams), saturated fat(grams) and sodium(milligrams) in care. A cross-sectional study amongst 448 children attending 22 childcare centres in New South Wales, Australia, was conducted. Child dietary intake was measured via weighed lunchbox measurements, photographs and researcher observation, and centre healthy eating practices were assessed via researcher observation of centre nutrition environments. Children attending lunchbox centres consumed, on average 0.80 servings (standard deviation 0.69) of fruit and 0.27 servings (standard deviation 0.51) of vegetables in care. The availability of foods within children’s lunchboxes was associated with intake of such foods (p < 0.01). Centre provision of intentional healthy eating learning experiences (estimate −0.56; p = 0.01) and the use of feeding practices that support children’s healthy eating (estimate −2.02; p = 0.04) were significantly associated with reduced child intake of saturated fat. Interventions to improve child nutrition in centres should focus on a range of healthy eating practices, including the availability of foods packed within lunchboxes.

AbstractLet G be a p–group with cyclic L(G) = Z. Then L(G) = {Z < H ≦ G|H′ ∩ Z = (1)}, a poset ordered under inclusion. Then the associated simplicial complex |L(G)| is homotopic to a bouquet of spheres. A subgroup E of G is called a CES if CG (E) = Z = L(E) and if E/Z is elementary. Then |L(G)| is homotopic to the one-point union of the |L(E)| for all CES's E in G. If |E/Z| = p2n then |L(E)| is homotopic to a one-point union of pn2 (n– 1)-spheres.

Abstract:

The Praya Computer Eduction Center is currently experiencing a decline in registration due to the lack of information that is widely disseminated to people who cannot be reached by previously used information media such as brochures, radio, newspapers and so on, therefore we need a medium that can be achieved by other alternatives. that can support the information spread widely, especially for those who are far away. In this study, the calculation of SUS data is used to determine the efficiency of this Education Information sistem. From the results of the blackbox test to sistem this information, it shows quite good results with no obstacles obtained when inputting, editing, deleting. For further follow-up, the management of the P-COM Education Center is expected to carry out more operations on this information sistem to obtain information SISTEM methods so that they can be used in the long term.

<p><em>Based on dance theorist insights into the basic components that determine performance of movements in dance, the article analyses promotion of a sense of bodily centre in classical and modern dance training. The most significant condition for a dancer to be able to fit within the confines of the proposed tasks in dance is to govern own body, which is made easier through an understanding of the body’s centre of gravity. Promoting an awareness of muscle activity being fixated within the central point of the body develops an understanding of movements around this point among dancers, which leads to easier control over performed movements. </em></p><p><em>The article aims to analyse the awareness of the body’s centre among dancers and to justify its significance in classical and modern dance training.

Abstract:

Background: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is associated with considerable postoperative morbidity, including ileus and infectious complications. Perioperative care is believed to be an important factor for the development and treatment of postoperative morbidity. Patients and Methods: Data on case-matched patients from a retrospective database of 2 Dutch HIPEC centres was compared. Patient selection and procedures were identical in both hospitals although perioperative management items differ slightly. In centre B, immediate total parenteral nutrition (TPN), suprapubic urine bladder catheter placement (SPCs) and selective decontamination of the digestive-tract are standard care for CRS-HIPEC patients, while in centre A, they are not. Results: From a total of 223 patients, 68 consecutive patients from centre B were compared to 68 matched patients from centre A. TPN was administered to 54.4% of patients in centre A because of prolonged ileus, whereas it was standard of care in centre B. In all, 105 (77.2%) patients experienced postoperative complications including 17.6% who had a grades III–IV complication. The incidence of grade III-V complications was 18 (26.4%) in centre A and 8 (11.8%) in centre B (p = 0.03). Median hospital stay was 12 days (7–84) in A and 11(6–80) in centre B (p = 0.546). Conclusions: Gastrointestinal recovery after CRS-HIPEC seems to take longer as compared to other surgical procedures. Between the 2 centres, a significant difference in severe complications was found, while standard TPN, selective bowel decontamination and SPCs were the only identified differences in perioperative care.

Abstract:

AbstractBackground:We aimed to conduct a multi-centre study characterising emergency department utilisation and critical readmissions experienced by children with Fontan circulation.Methods:We conducted a retrospective review of children who underwent the Fontan operation at three institutions (i.e., centres A, B, and C) between 2009 and 2014, with follow-up through December 2015. Multi-variable analyses were performed to determine factors associated for emergency department utilisation within 1 year of surgery, emergency department utilisation at any time following surgery, or critical readmission (defined as admission to ICU, operating room, or cardiac catheterisation).Results:We reviewed 297 patients, of which 147 patients (49%) had 607 emergency department encounters. Forty-six patients (15%) required 71 critical readmissions. Multi-variable analyses revealed centre C (p = 0.02) and post-operative hospitalisation ≥ 14 days (p = 0.03) to be significantly associated with emergency department utilisation within 1 year, whereas centre B (p < 0.001), post-operative hospitalisation ≥ 14 days (p = 0.002), and African-American/Black race (p = 0.04) were significantly associated with critical readmission.Conclusions:In this multi-centre study, nearly half of patients with Fontan circulation received emergency department care, often presenting with high disease acuity requiring readmission. Emergency department utilisation and need for critical readmission were independently influenced by the centre at which surgery was performed, prolonged post-operative hospitalisation, and racial background. These data could help guide quality improvement efforts aimed at reducing morbidity in this unique patient population.

Abstract:

A new study, by electron paramagnetic resonance (EPR) spectroscopy at cryogenic temperatures, of aluminum oxygenic-hole centres in a α-quartz single crystal is reported. The well-known centre [AlO4]0 has been reinvestigated with somewhat improved techniques and computer analysis, confirming previous results in the literature. A previously unreported AlLi centre has now been well characterized by EPR. From the fitted parameter matrices g, A(27Al), P(27Al), A(7Li), and P(7Li) we have determined not only that the hole resides on a "long-bonded" oxygen anion, as in [AlO4]0, but have also established the position of the near-by interstitial lithium ion. One model for this centre is that it consists of a lithium atom Li0 linked to the diamagnetic centre [AlO4], yielding hole-bearing species [AlO4/Li] via internal charge transfer.

Abstract:

Objective: To determine the prognostic value of patient and treatment parameters in osteosarcoma, and whether these are equally important across international boundaries.Design: Retrospective, cross-sectional study of 428 patients diagnosed with around-knee osteosarcoma, between 1990 and 1997 in Birmingham, UK, and Bologna, Italy. Disease-free survival (DFS) and overall survival (OS) assessed by Kaplan–Meier, Fisher's PLSD and Cox proportional hazard regression.Results: Five-year DFS and OS were 56 and 73% at Centre 1, compared to 43 and 60% at Centre 2 (P=0.0022 andP= 0.025, respectively). The most important bad prognostic factors for DFS and OS respectively were raised alkaline phosphatase at diagnosis (P=0.002 andP=0.003), tumour necrosis < 90% following chemotherapy (P=0.001 andP= 0.004) and volume > 150cm3at diagnosis (P=0.04 andP=0.006). The most significant combination of bad prognostic factors was alkaline phosphatase and tumour necrosis. A total of 73% of patients at Centre 1 had greater than 90% necrosis of the tumour following neoadjuvant chemotherapy compared with 29% at Centre 2.Conclusions: Tumour-based prognostic factors have similar significance across international boundaries. Chemotherapy effectiveness appears to be a major factor in explaining the survival difference between the two centres.

Abstract:

AbstractIntroductionChylothorax after paediatric cardiac surgery incurs significant morbidity; however, a detailed understanding that does not rely on single-centre or administrative data is lacking. We described the present clinical epidemiology of postoperative chylothorax and evaluated variation in rates among centres with a multicentre cohort of patients treated in cardiac ICU.MethodsThis was a retrospective cohort study using prospectively collected clinical data from the Pediatric Cardiac Critical Care Consortium registry. All postoperative paediatric cardiac surgical patients admitted from October, 2013 to September, 2015 were included. Risk factors for chylothorax and association with outcomes were evaluated using multivariable logistic or linear regression models, as appropriate, accounting for within-centre clustering using generalised estimating equations.ResultsA total of 4864 surgical hospitalisations from 15 centres were included. Chylothorax occurred in 3.8% (n=185) of hospitalisations. Case-mix-adjusted chylothorax rates varied from 1.5 to 7.6% and were not associated with centre volume. Independent risk factors for chylothorax included age <1 year, non-Caucasian race, single-ventricle physiology, extracardiac anomalies, longer cardiopulmonary bypass time, and thrombosis associated with an upper-extremity central venous line (all p<0.05). Chylothorax was associated with significantly longer duration of postoperative mechanical ventilation, cardiac ICU and hospital length of stay, and higher in-hospital mortality (all p<0.001).ConclusionsChylothorax after cardiac surgery in children is associated with significant morbidity and mortality. A five-fold variation in chylothorax rates was observed across centres. Future investigations should identify centres most adept at preventing and managing chylothorax and disseminate best practices.

Abstract:

The paper generally aimed to study the effect of the internal control system on the financial performance of church organization compassion centres in the Nyamagana district. Specifically, the study centred on three areas, namely, the control environment, control activities and monitoring. The study applied the principal/agency theory. Data were collected at once through close-ended questionnaires where a cross-sectional research design was fitted. The study’s unity of analysis involved 100 people (church leaders, compassion centre board members, personal coordinators, social workers, accountants, and auditors). A binary logistic regression was used to analyze the relationship between the internal control system (ICS) and financial performance (FP) of church organization compassion centres. The outcomes depicted that the control environment has a positive significant relationship with the FP of compassion centres (r=0.838, β=0.512, p=0.000). Moreover, control activities have a positive significant relationship (r=0.828, β=0.521, p=0.000), while monitoring has a positive significant relationship with FP of compassion centres (r=0.751, β=0.629, p=0.000).

Abstract:

This study aimed to assess the effect of the county-level medical centre policy on the health outcomes of trauma patients transported by emergency medical service (EMS) system in rural China. The methodology involved the use of electronic health records (EHRs, after 2016) of patients with trauma conditions such as head injury (n = 1931), chest (back) injury (n = 466), abdominal (waist) injury (n = 536), and limb injury (n = 857) who were transported by EMS to the county-level trauma centres of Huining County and Huan County in Gansu, China. Each patient was matched with a counterpart to a county-level trauma centre hospital by propensity score matching. Cox proportional hazard models were used to estimate the hazard ratios (HRs) of such patients in different hospitals. The HRs of all patients with the abovementioned traumatic conditions transported by EMS to county-level trauma centre hospitals were consistently higher than those transported by EMS to traditional hospitals after adjusting for numerous potential confounders. Higher HRs were associated with all patients with trauma (HR = 1.249, p < 0.001), head injury (HR = 1.416, p < 0.001), chest (back) injury (HR = 1.112, p = 0.560), abdominal (waist) injury (HR = 1.273, p = 0.016), and limb injury (HR = 1.078, p = 0.561) transported by EMS to the county-level trauma centre hospitals. Our study suggests that the construction of county-level medical centre provides an effective strategy to improve the health outcomes of EMS-transported trauma patients in Gansu, China. Policy makers can learn from the experience and improve the health outcomes of such patients through a personalised trauma treatment system and by categorizing the regional trauma centre.

Abstract:

Background: The use of high-fidelity simulation is emerging as a desirable method for competency-based assessment in postgraduate medical education. We aimed to demonstrate the feasibility and validity of a multi-centre simulation-based Objective Structured Clinical Examination (OSCE) of resuscitation competence with Canadian Emergency Medicine (EM) trainees.Method: EM postgraduate trainees (n=98) from five Canadian academic centres participated in a high fidelity, 3-station simulation-based OSCE. Expert panels of three emergency physicians evaluated trainee performances at each centre using the Queen’s Simulation Assessment Tool (QSAT). Intraclass correlation coefficients were used to measure the inter-rater reliability, and analysis of variance was used to measure the discriminatory validity of each scenario. A fully crossed generalizability study was also conducted for each examination centre. Results: Inter-rater reliability in four of the five centres was strong with a median absolute intraclass correlation coefficient (ICC) across centres and scenarios of 0.89 [0.65-0.97]. Discriminatory validity was also strong (p < 0.001 for scenarios 1 and 3; p < 0.05 for scenario 2). Generalizability studies found significant variations at two of the study centres.Conclusions: This study demonstrates the successful pilot administration of a multi-centre, 3-station simulation-based OSCE for the assessment of resuscitation competence in post-graduate Emergency Medicine trainees.

Abstract:

AimsTo compare the Emergency Department (ED) referrals to psychiatry in a suburban versus an urban setting over a one-month to evaluate mental health presentations characteristics across two locations.MethodThis study was a retrospective cross-sectional study examining ED referrals to psychiatry in an inner-city and suburban centre over one month; - one based in an inner-city setting, the other based in a suburban area outside the city. The anonymised data were collected from both hospital's electronic patient records and analysed. The authors collected data on gender, age, employment, housing, the clinical problem at presentation, time of assessment and admissions. Descriptive data and hypothesis testing were performed where appropriate using Statistical Package for Social Sciences SPSS® version 26.ResultThe total number referred was 213: inner-city n = 109 and suburban n = 104. The inner-city saw a younger population; 47/109 (43%) were aged between 20 and 29 years, compared with 28/104 (27%) of suburban presenters (P-value 0.0134). A higher number of presenters were aged over 60 years in the suburban centre n = 13/104 (12.5%) versus the inner-city centre 3/109 (2.8%) (P-value 0.0084). In the inner-city, the proportion of homeless presenters was significantly higher at 30/109 (28%) versus 5/104 (4.8%) in the suburban setting (P < 0.0001). Presentations related to substances were highest, a total of 73 (34.3%) across both centres, with no significant difference in clinical presentations across the two centres. The majority were seen in the on-call period, 74/109 (67.9%) in the inner-city centre and 66/104 (63.5%) in the suburban centre. The psychiatric admission rate was significantly different between the two centres, with 33/109 (30.3%) patients admitted to the inner-city centre and 13/104 (12.5%) patients admitted to the suburban centre (P-value 0.002).ConclusionA large proportion of ED referrals to psychiatry constitute patients with unmet social and addiction needs. The variance in capabilities of liaison psychiatry (LP) and ED services means the local population's needs may not always be adequately catered for within a typical LP setting, which in the Irish context is predominantly driven by medical and nursing staff. This study highlights many patients attend the ED who may be better assessed directly by the community as per our National Emergency Program policies. This prompts consideration of expanding both ED and community services to comprise a more integrated, multidisciplinary-resourced, 24/7 care model.

Abstract:

Abstract Introduction In patients with ST-elevation myocardial infarction (STEMI), percutaneous coronary intervention (PCI)-mediated reperfusion is preferred over pharmacoinvasive reperfusion with fibrinolysis if transfer to a PCI centre can be ensured in ≤120 min. We evaluated the ambulance driving time to primary PCI centres in the Netherlands and assessed to what extent ambulance driving times were impacted by the expansion of off-site PCI centres. Methods and results We calculated the driving routes from every Dutch postal code to the nearest PCI centre with (on-site) or without (off-site) surgical back-up. We used data from ambulance records to estimate the ambulance driving time on each route. There were 16 on-site and 14 off-site PCI centres. The median (interquartile range) time to on-site PCI centres was 18.8 min (12.2–26.3) compared with 14.9 min (8.9–20.9) to any PCI centre (p < 0.001). In postal code areas that were impacted by the initiation of off-site PCI, the median driving time decreased from 25.4 (18.2–33.1) to 14.7 min (8.9–20.9) (p < 0.001). Ambulance driving times of >120 min were only seen in non-mainland areas. Conclusion Based on a computational model, timely ambulance transfer to a PCI centre within 120 min is available to almost all STEMI patients in the Netherlands. Expansion of off-site PCI has significantly reduced the driving time to PCI centres.

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.

Abstract:

<p>This paper is an attempt to develop a new way to sell products or services for retailers within town centres. An analysis of the literature revealed that the use of the Internet and digital commerce strategies are rarely used as tools to revitalize urban retail and develop a multidimensional experience of place. Thus, this paper aims to highlight which new modes of online commerce—e-commerce, s-commerce and m-commerce—are more suitable than others to help town centre retailers revitalize the place where they work. The research questions are as follows: 1) What are the origins of the growth and development of new forms of selling? and 2) How might town centre retailers integrate new forms of selling with traditional retailing? In answering the previously stated questions, this paper provides a proposed model that, by combining physical and virtual means to sell products and services, can provide specific strengths in revitalizing town centres.</p>

Abstract:

We examined how a mixture of Pinus radiata D. Don and Cupressus lusitanica Mill. influences foliage element concentrations at 20 sites, covering a fertility gradient. Foliage element concentrations of plants at plot boundaries, where the two species grew adjacent to each other, were compared with those of plants at plot centres, where they were surrounded by plants of the same species. For C. lusitanica, plot position significantly affected nitrogen (N), phosphorus (P), and sulphur (S) with concentrations of these elements at the plot boundary exceeding concentrations at the plot centre by 10%–14%. For P. radiata, plants at the plot boundary had a significantly greater P concentration and lower N/P ratio than plants at the centre, but differences between positions were less than that for C. lusitanica (<7%). For C. lusitanica, the difference between foliage concentrations of N and P at the plot boundary and centre significantly declined as the mean plot concentrations of these elements increased. It is likely that C. lusitanica at the boundary benefited from the greater availability of N, P, and S in the root rhizosphere, where they were mobilized from soil organic matter by the ectomycorrhizae of P. radiata. We also suggest that P. radiata at the plot boundary may have benefited from mobilization of P by the endomycorrhizae of C. lusitanica.
