RESUMEN

INTRODUCTION: Surgical training programmes in the United Kingdom and Ireland (UK&I) are in a state of flux. This study aims to report the contemporary opinions of trainee and consultant surgeons on the current upper gastrointestinal (UGI) training model in the UK&I. METHODS: A questionnaire was developed and distributed via national UGI societies. Questions pertained to demographics, current training evaluation, perceived requirements and availability. RESULTS: A total of 241 responses were received with representation from all UK&I postgraduate training regions. The biggest discrepancies between rotation demand and national availability related to advanced/therapeutic endoscopy and robotic surgery, with 91.7% of respondents stating they would welcome greater geographical flexibility in training. The median suggested academic targets were 3-5 publications (trainee vs consultant <3 vs 3-5, p<0.001); <3 presentations (<3 vs 3-5, p=0.002); and 3-5 audits/quality improvement projects (<3 vs 3-5, p<0.001). Current operative requirements were considered achievable (87.6%) but inadequate for day one consultant practice (74.7%). Reassuringly, 76.3% deemed there was role for on-the-job operative training following consultant appointment. Proficiency in diagnostic endoscopy was considered a minimum requirement for Certificate of Completion of Training (CCT) yet the majority regarded therapeutic endoscopy competency as non-essential. The median numbers of index UGI operations suggested were comparable with the current curriculum requirements. Post-CCT fellowships were not considered necessary; however, the majority (73.6%) recognised their advantage. CONCLUSIONS: Current CCT requirements are largely consistent with the opinions of the UGI community. Areas for improvement include flexibility in geographical working and increasing national provisions for high-quality endoscopy training.

RESUMEN

BACKGROUND: Research on the impact of the US President's Emergency Plan for AIDS Relief (PEPFAR) transition in South Africa (SA) in 2012 found varying results in retention in care (RIC) of people living with HIV (PLWH). OBJECTIVES: To investigate the factors that impacted RIC during the PEPFAR transition in Western Cape Province, SA, in 2012. METHODS: We used aggregate data from 61 facilities supported by four non-governmental organisations from 2007 to 2015. The main outcome was RIC 12 months after antiretroviral therapy initiation for two periods - during PEPFAR and post PEPFAR. We used adjusted quantile regression to estimate the effect of the PEPFAR pull-out on RIC. RESULTS: Regression models (50th quantile) for 12-month RIC showed a 4.0% (95% CI -7.7 - -0.4%) decline in RIC post-direct service. Facilities supported by Anova/Kheth'impilo fared worst post PEFPAR, with a decline in RIC of -4.9% (95% CI -8.8 - -1.0%), while TB, HIV/AIDS, Treatment Support, and Integrated Therapy (that'sit) fared best (3.6% increase in RIC; 95% CI: -0.2 - 7.3%). There was a decrease in RIC when comparing urban with rural areas (-7.8%; 95% CI -12.8 - -2.9%). City of Cape Town combined with Western Cape Government health facilities showed a substantial decrease (-6.1%; 95% CI -10.6 - -1.7%), while community health clinic (v. central day clinics) declined (-6.4; 95% CI -10.6 - -2.1%) in RIC. We observed no RIC difference by facility size and a slight increase when two or more human resources transitioned from PEPFAR to the government. CONCLUSION: When PEPFAR funding decreased in 2012, there was a decrease in RIC. To ensure the continuity of HIV care when a major funder withdraws sufficient and stable transition resources, investment in organisations that understand the local context, joint planning and co-ordination are required.

RESUMEN

BACKGROUND: Ex vivo normothermic machine liver perfusion (NMLP) involves artificial cannulation of vessels and generation of flow pressures. This could lead to shear stress-induced endothelial damage, predisposing to vascular complications, or improved preservation of donor artery quality. This study aims to assess the spatial donor hepatic artery (HA) endothelial quality downstream of the cannulation site after end-ischaemic NMLP. METHODS: Remnant HA segments from the coeliac trunk up to the gastroduodenal artery branching were obtained after NMLP (n = 15) and after static cold storage (SCS) preservation (n = 15). Specimens were fixed in 10% neutral buffered formalin and sectioned at pre-determined anatomical sites downstream of the coeliac trunk. CD31 immunohistostaining was used to assess endothelial integrity by a 5-point ordinal scale (grade 0: intact endothelial lining, grade 5: complete denudation). Endothelial integrity after SCS was used as a control for the state of the endothelium at commencement of NMP. RESULTS: In the SCS specimens, regardless of the anatomical site, near complete endothelial denudation was present throughout the HA (median scores 4.5-5). After NMLP, significantly less endothelial loss in the distal HA was present compared to SCS grafts (NMLP vs. SCS: median grade 3 vs. 4.5; p = 0.042). In NMLP specimens, near complete endothelial denudation was present at the cannulation site in all cases (median grade: 5), with significantly less loss of the endothelial lining the further from the cannulation site (proximal vs. distal, median grade 5 vs. 3; p = 0.005). CONCLUSION: Loss of endothelial lining throughout the HA after SCS and at the cannulation site after NMLP suggests extensive damage related to surgical handling and preservation injury. Gradual improved endothelial lining along more distal sites of the HA after NMLP indicates potential for re-endothelialisation. The regenerative effect of NMLP on artery quality seems to occur to a greater extent further from the cannulation site. Therefore, arterial cannulation for machine perfusion of liver grafts should ideally be as proximal as possible on the coeliac trunk or aortic patch, while the site of anastomosis should preferentially be attempted distal on the common HA.

RESUMEN

BACKGROUND: Cauda equina syndrome, a rare but disabling spinal surgical emergency, requires prompt investigation, ideally using magnetic resonance imaging as patients may require decompressive surgery. Out of hours access to magnetic resonance imaging is only routinely available in major trauma centres and neurosurgical units. Patients in regional hospitals with suspected cauda equina syndrome may require transfer for diagnostic imaging. We retrospectively studied the proportion of patients referred with suspected cauda equina syndrome who required out of hours transfer for magnetic resonance imaging and decompressive surgery. MATERIALS ANDS METHODS: Retrospective cohort study of patients referred using online referral platforms with suspected acute cauda equina syndrome and transferred out of hours between 6pm to 8am on weekdays and all day on weekends to two of the largest neurosurgical units in the UK in Birmingham and Cambridge. RESULTS: A total of 441 patients were referred across both sites with a suspicion of acute cauda equina syndrome; 339 patients were transferred for diagnostic scans and only 16 of them (4.7%) were positive for cauda equina compression, necessitating prompt decompressive surgery. Of the patients with negative magnetic resonance scans, 50% had their discharge or transfer back to referring hospitals delayed by more than 24 hours. CONCLUSIONS: Over 95% of patients who were transferred for imaging did not undergo emergency decompression. The authors propose a greater role for the provision of out of hours magnetic resonance imaging in all hospitals admitting emergency patients to streamline management.

RESUMEN

INTRODUCTION: Asthma is a chronic condition affecting between 300 and 400 million people worldwide. Studies have shown that asthma symptoms can be controlled by the daily use of inhaled corticosteroids (ICS). The management of asthma varies in different settings.METHODS: Asthma management in 13 sub-Saharan African countries was compared to the 2018 Global Initiative for Asthma (GINA) guidelines and the 20th WHO model list of essential medicines (2019). A table with predefined criteria extracted from the international guidelines was used to analyse the content and compare the different treatment guidelines using an Excel spreadsheet.RESULTS: There are variations in the way asthma is diagnosed and treated in different countries. Countries with older treatment guidelines do not have a stepwise approach to assessing severity as stipulated by GINA. Of the 13 countries, only 46% have inhaled ICS at the primary level, 38% have ICS at the secondary level and 16% do not specify.CONCLUSION: The management of asthma varies widely between different countries in sub-Saharan Africa. The noticed variations in approach to care can be explored as an opportunity to harness resources to produce similar and updated guidelines, resulting in uniformity of care across different countries.

RESUMEN

OBJECTIVE: In spite of the increasing number of global health partnerships led by biopharmaceutical companies, there is a paucity of information on the number, type, and role of partners. This paper aims to analyze partnerships carrying out company programs included in Access Accelerated, a new industry initiative, focused on addressing the global non-communicable disease burden. STUDY DESIGN: Document review and content analysis. METHODS: We extracted data on the number, type, and role of partners from 63 company programs reported into the Access Observatory, a public platform for reporting on access-to-medicines programs, in 2017. We did a descriptive analysis of the proportion of partners by sector, institution, and location. We used the Fischer's exact test to analyze the relationship between the program strategies, disease focus, and countries with the type of program partners. Based on our empirical findings, we developed a typology of program partnerships, according to which we categorized each of the 63 programs. RESULTS: Programs worked with three partners on average, the majority of which were local governmental or non-governmental organizations (70%). Most programs focused on health service strengthening (83%), community awareness and linkage to care (81%), and health service delivery (60%). Twenty-six of the 63 programs (41%) worked with the local Ministries of Health while 25 (40%) partnered with disease-specific organizations, 21 (33%) with hospitals, and 16 (25%) with academic institutions. Partnering with the Ministries of Health was significantly associated with the use of a health service strengthening program strategy (P = 0.02). Partnering with a hospital (P = 0.004) or private sector partner (P = 0.0009) was significantly associated with a program disease focus on cancer. Seventy-nine percent of the programs were solely funded by pharmaceutical companies. According to our program typology, 40 (63%) programs partnered directly or indirectly with multiple implementing organizations, which delivered the program directly to beneficiaries. CONCLUSION: Pharmaceutical companies play a leading role in funding Access Accelerated programs with local governmental or non-governmental organizations mainly involved in program implementation. A detailed and transparent reporting of the role of local stakeholders in agenda setting, planning, and coordination of programs is needed to ensure public trust and accountability of programs led by pharmaceutical companies. More research is needed to identify the partnerships that are particularly suitable to promote efficient implementation, evaluation, and reporting depending on the nature of the program and context.

RESUMEN

AIM: To describe the global insulin market. METHODS: Market intelligence data, United Nations Commodity Trade Statistics for insulin trade, the International Medical Products Price Guide for prices of human insulin and additional web searches were used as data sources. These sources were combined to gain further insight into possible links among market, trade flows and prices. Descriptive statistics and Spearman's rank order correlation were used for the analysis. RESULTS: A total of 34 insulin manufacturers were identified. Most countries and territories are reliant on a limited number of supplying countries. The overall median (interquartile range) government procurement price for a 10-ml, 100-IU/ml vial during the period 1996-2013 equivalent was US$4.3 (US$ 3.8-4.8), with median prices in Africa (US$ 4.7) and low- (US$ 6.9) and low- to middle- (US$ 4.7) income countries being higher over this period. The relationships between price and quantity of insulin (Spearman's r=0.046; P>0.1) and number of import links (Spearman's r=0.032; P>0.1) were weak. The links between price and percentage of total insulin from a country where a 'big three' manufacturer produces insulin (Spearman's r=0.294; P<0.05) and total insulin from the main import link (Spearman's r=-0.392; P<0.05) were stronger. CONCLUSIONS: This research shows the high variability of insulin prices and the reliance on a few sources, both companies and countries, for global supply. In addressing access to insulin, countries need to use existing price data to negotiate prices, and mechanisms need to be developed to foster competition and security of supply of insulin, given the limited number of truly global producers.

RESUMEN

BACKGROUND: Liver transplantation is the only life-extending intervention for primary sclerosing cholangitis (PSC). Given the co-existence with colitis, patients may also require colectomy; a factor potentially conferring improved post-transplant outcomes. AIM: To determine the impact of restorative surgery via ileal pouch-anal anastomosis (IPAA) vs retaining an end ileostomy on liver-related outcomes post-transplantation. METHODS: Graft survival was evaluated across a prospectively accrued transplant database, stratified according to colectomy status and type. RESULTS: Between 1990 and 2016, 240 individuals with PSC/colitis underwent transplantation (cumulative 1870 patient-years until first graft loss or last follow-up date), of whom 75 also required colectomy. A heightened incidence of graft loss was observed for the IPAA group vs those retaining an end ileostomy (2.8 vs 0.4 per 100 patient-years, log-rank P = 0.005), whereas rates between IPAA vs no colectomy groups were not significantly different (2.8 vs 1.7, P = 0.1). In addition, the ileostomy group experienced significantly lower graft loss rates vs. patients retaining an intact colon (P = 0.044). The risks conferred by IPAA persisted when taking into account timing of colectomy as related to liver transplantation via time-dependent Cox regression analysis. Hepatic artery thrombosis and biliary strictures were the principal aetiologies of graft loss overall. Incidence rates for both were not significantly different between IPAA and no colectomy groups (P = 0.092 and P = 0.358); however, end ileostomy appeared protective (P = 0.007 and 0.031, respectively). CONCLUSION: In PSC, liver transplantation, colectomy + IPAA is associated with similar incidence rates of hepatic artery thrombosis, recurrent biliary strictures and re-transplantation compared with no colectomy. Colectomy + end ileostomy confers more favourable graft outcomes.

RESUMEN

BACKGROUND: It is estimated that about 4 million Kenyans, i.e., 10% of the country's population, have asthma. We aimed to evaluate access to asthma medicines at the household level in eight counties of Kenya, including factors associated with location of purchase. METHODS: Individuals with a diagnosis and prescription of asthma medicines were asked about the location of diagnosis, purchase of medicines, availability of medicines at home and costs of medicines per month. A logistic regression model explored the relationship between patient characteristics and the probability that the patient purchased asthma medicines at a public facility. RESULTS: Of 128 (15.2%) individuals with a diagnosis of asthma who were receiving treatment, only 57.0% had asthma medicines at home. The most frequently purchased asthma medicine was salbutamol, with one third of individuals taking it orally instead of by inhalation. The majority (55.4%) purchased asthma medicines at private pharmacies. Female patients and lower socio-economic status were predictors of purchasing asthma medicines at public facilities. CONCLUSIONS: The availability and affordability of asthma medicines remain significant barriers to access to care. Improving the availability and affordability of all asthma medicines in the public sector, including inhaled corticosteroids, offers the opportunity to reach vulnerable populations.

RESUMEN

AIMS: To assess long-term outcomes and resource use of 4D Brachytherapy, a one-stage real-time implant for the treatment of prostate cancer that uses stranded and loose iodine-125 seeds, and to compare with the conventional two-stage (2S) technique. MATERIALS AND METHODS: Prospectively collected data of men who underwent 2S and 4D low dose rate brachytherapy in a single institution were analysed. Survival estimates were analysed using the Kaplan-Meier method and Log-rank test. Treatment failure rates were further compared by Cox proportional hazards (Coxph) regression or by a surrogate prostate-specific antigen value cut-off of 0.4 ng/ml 48 months post-implant. Treatment toxicity outcomes were also evaluated. Comparative costs were based on published English National Health Service data. RESULTS: We compared outcomes of 690 men treated with 2S and 1031 men with 4D brachytherapy. Median follow-up times were 10.4 and 5.2 years (P < 0.001) for 2S and 4D cases, respectively. Day 0 post-implant dosimetry was improved in 4D brachytherapy patients. Five years post-implant ≥98% of cases were alive and ≥95% were free from disease relapse irrespective of technique. Coxph regression showed the risk of relapse after 4D brachytherapy was similar to the 2S technique (hazard ratio 0.67, 95% confidence interval 0.44-1.03, P = 0.065). Forty-eight months post-implant there was a significantly greater proportion of 4D brachytherapy cases with a prostate-specific antigen below 0.4 ng/ml relative to the 2S technique. Urinary and bowel symptom scores showed reduced toxicity after 4D implants and potency conservation was similar to the 2S technique. The reduction in time and resource use decreased the cost of 4D brachytherapy by 40% compared with the 2S technique. CONCLUSION: Two-stage and 4D brachytherapy are both highly effective for the control of localised prostate cancer. However, relative to the 2S technique, the 4D technique was associated with improved dosimetry, reduced treatment-related toxicity and reduced cost. Further follow-up will assess disease control superiority of 4D brachytherapy beyond 5 years post-implant.

RESUMEN

Objectives To describe and understand the determinants of patients' behaviours surrounding admission to hospital for an acute infective episode Method Patients admitted to the infection or acute medicine admission units of a major Scottish teaching hospital and commenced on antibiotic therapy after admission were included. Semi-structured face-to-face interviews were conducted using a pre-piloted interview schedule guide that focused on gathering information about patient behaviours and experiences prior to admission to hospital with an acute infection. Interviews were audio-recorded, transcribed verbatim and analysed using the Framework Approach. Emerging themes were matched to the Theoretical Domains Framework of behavioural determinants. Results Twenty-one patients consented to participate and 18 transcripts were suitable for analysis. The most common infections were those of the skin, soft tissue and respiratory tract. From the patients' perspectives, behavioural determinants that appeared to impact their admission to hospital were principally their knowledge, beliefs of consequences, the environmental context and resources (mainly out-of-hours services), social influences and their own emotions. Determinants such as knowledge of the signs and symptoms, beliefs of consequences and environmental context were facilitators of health seeking behaviours. The main barriers were a lack of awareness of consequences of infection potentially leading to delayed admission impacting infection severity, stay in secondary care and resource utilisation. Conclusions This study has shown that any initial patient-centred intervention that is proposed to change patient behaviour needs to be based on behavioural determinants emerging in this research. The intervention may include aspects such as patient education on resources available out-of-hours and ways to access the healthcare system, education on recognising signs of infection leading to prompter treatment and positive reinforcement for patients who present with recurrences of infection.

RESUMEN

BACKGROUND: To assess the effect of policies supporting local medicine production to improve access to medicines. METHODS: We adapted the WHO/HAI instruments measuring medicines availability and prices to differentiate local from imported products, then pilot tested in Ethiopia and Tanzania. In each outlet, prices were recorded for all products in stock for medicines on a country-specific list. Government procurement prices were also collected. Prices were compared to an international reference and expressed as median price ratios (MPR). RESULTS: The Ethiopian government paid more for local products (median MPR = 1.20) than for imports (median MPR = 0.84). Eight of nine medicines procured as both local and imported products were cheaper when imported. Availability was better for local products compared to imports, in the public (48% vs. 19%, respectively) and private (54% vs. 35%, respectively) sectors. Patient prices were lower for imports in the public sector (median MPR = 1.18[imported] vs. 1.44[local]) and higher in the private sector (median MPR = 5.42[imported] vs. 1.85[local]). In the public sector, patients paid 17% and 53% more than the government procurement price for local and imported products, respectively. The Tanzanian government paid less for local products (median MPR = 0.69) than imports (median MPR = 1.34). In the public sector, availability of local and imported products was 21% and 32% respectively, with patients paying slightly more for local products (median MPR = 1.35[imported] vs. 1.44[local]). In the private sector, local products were less available (21%) than imports (70%) but prices were similar (median MPR = 2.29[imported] vs. 2.27[local]). In the public sector, patients paid 135% and 65% more than the government procurement price for local and imported products, respectively. CONCLUSIONS: Our results show how local production can affect availability and prices, and how it can be influenced by preferential purchasing and mark-ups in the public sector. Governments need to evaluate the impact of local production policies, and adjust policies to protect patients from paying more for local products.

RESUMEN

BACKGROUND: Approximately 40% of hormone receptor-positive, HER2-negative breast cancers (BCs) are associated with activating mutations of the phosphatidylinositol 3-kinase (PI3K) pathway. Pictilisib, a potent and highly specific class I pan-PI3K inhibitor, demonstrated preclinical activity in BC cell lines and may potentiate the effect of taxanes, benefiting patients with or without aberrant activation of the PI3K pathway. PEGGY (NCT01740336), a randomised, placebo-controlled phase II trial, examined whether pictilisib augments the anti-tumour activity of paclitaxel in patients with hormone receptor-positive, HER2-negative locally recurrent or metastatic BC (mBC). We report results from the protocol-specified interim analysis. PATIENTS AND METHODS: One hundred and eighty-three eligible patients were randomised (1:1) to receive paclitaxel (90 mg/m2 weekly for 3 weeks in every 28-day cycle) with either 260 mg pictilisib or placebo (daily on days 1-5 every week). The primary end point was progression-free survival (PFS) in the intention-to-treat (ITT) population and patients with PIK3CA-mutated tumours. Secondary end points included overall response rate (ORR), duration of response, and safety. RESULTS: In the ITT population, the median PFS was 8.2 months with pictilisib (n = 91) versus 7.8 months with placebo (n = 92) [hazard ratio (HR) for progression or death, 0.95; 95% confidence interval (CI) 0.62-1.46; P = 0.83]. In patients with PIK3CA-mutated tumours, the median PFS was 7.3 months for pictilisib (n = 32) versus 5.8 months with placebo (n = 30) (HR, 1.06; 95% CI 0.52-2.12; P = 0.88). ORR was similar between treatment arms. The safety profile of pictilisib was consistent with previous reports, with no new safety signals. Proportions of patients with grade ≥3 adverse events (AEs), serious AEs, and dose reductions/discontinuations due to AEs were higher with pictilisib. CONCLUSIONS: PEGGY did not meet its primary end point, revealing no significant benefit from adding pictilisib to paclitaxel for patients with hormone receptor-positive, HER2-negative locally recurrent or mBC. CLINICAL TRIAL NUMBER: NCT01740336.

RESUMEN

We were tasked with creating best possible non-clinical workspace solutions for approximately 450 hospital staff across 11 departments encompassing medical, nursing, allied health, administrative and other support staff. We used a Human-Centred Design process, involving 'Hear, Create and Deliver' stages. We used observations, contextual enquiry and role-specific workshops to understand needs, key interactions and drivers of behaviour. Co-design workshops were then used to explore and prototype-test concepts for the final design. With extensive employee engagement and design process expertise, an innovative solution was created that focussed on meeting the functional workspace needs of a diverse group of staff requiring a range of different spaces, incorporating space constraints and equity. This project demonstrated the strength of engaging employees in an expert-led Human-Centred Design process. We believe this is a successful blueprint process for other institutions to embrace when facing similar workspace design challenges.

RESUMEN

The demand for liver transplantation (LT) exceeds supply, with rising waiting list mortality. Utilization of high-risk organs is low and a substantial number of procured livers are discarded. We report the first series of five transplants with rejected livers following viability assessment by normothermic machine perfusion of the liver (NMP-L). The evaluation protocol consisted of perfusate lactate, bile production, vascular flows, and liver appearance. All livers were exposed to a variable period of static cold storage prior to commencing NMP-L. Four organs were recovered from donors after circulatory death and rejected due to prolonged donor warm ischemic times; one liver from a brain-death donor was declined for high liver function tests (LFTs). The median (range) total graft preservation time was 798 (range 724-951) min. The transplant procedure was uneventful in every recipient, with immediate function in all grafts. The median in-hospital stay was 10 (range 6-14) days. At present, all recipients are well, with normalized LFTs at median follow-up of 7 (range 6-19) months. Viability assessment of high-risk grafts using NMP-L provides specific information on liver function and can permit their transplantation while minimizing the recipient risk of primary graft nonfunction. This novel approach may increase organ availability for LT.

RESUMEN

One of the first genome sequencing projects for a parasitic nematode was that for Haemonchus contortus. The open access data from the Wellcome Trust Sanger Institute provided a valuable early resource for the research community, particularly for the identification of specific genes and genetic markers. Later, a second sequencing project was initiated by the University of Melbourne, and the two draft genome sequences for H. contortus were published back-to-back in 2013. There is a pressing need for long-range genomic information for genetic mapping, population genetics and functional genomic studies, so we are continuing to improve the Wellcome Trust Sanger Institute assembly to provide a finished reference genome for H. contortus. This review describes this process, compares the H. contortus genome assemblies with draft genomes from other members of the strongylid group and discusses future directions for parasite genomics using the H. contortus model.

RESUMEN

The use of livers from donation after circulatory death (DCD) is increasing, but concerns exist regarding outcomes following use of grafts from "marginal" donors. To compare outcomes in transplants using DCD and donation after brain death (DBD), propensity score matching was performed for 973 patients with chronic liver disease and/or malignancy who underwent primary whole-liver transplant between 2004 and 2014 at University Hospitals Birmingham NHS Foundation Trust. Primary end points were overall graft and patient survival. Secondary end points included postoperative, biliary and vascular complications. Over 10 years, 234 transplants were carried out using DCD grafts. Of the 187 matched DCDs, 82.9% were classified as marginal per British Transplantation Society guidelines. Kaplan-Meier analysis of graft and patient survival found no significant differences for either outcome between the paired DCD and DBD patients (p = 0.162 and p = 0.519, respectively). Aspartate aminotransferase was significantly higher in DCD recipients until 48 h after transplant (p < 0.001). The incidences of acute kidney injury and ischemic cholangiopathy were greater in DCD recipients (32.6% vs. 15% [p < 0.001] and 9.1% vs. 1.1% [p < 0.001], respectively). With appropriate recipient selection, the use of DCDs, including those deemed marginal, can be safe and can produce outcomes comparable to those seen using DBD grafts in similar recipients.

RESUMEN

AIMS: This audit provides a comprehensive overview of UK prostate brachytherapy practice in the year 2012, measured against existing standards, immediately before the introduction of new Royal College of Radiologists (RCR) guidelines. This audit allows comparison with European and North American brachytherapy practice and for the impact of the RCR 2012 guidelines to be assessed in the future. MATERIALS AND METHODS: A web-based data collection tool was developed by the RCR Clinical Audit Committee and sent to audit leads at all cancer centres in the UK. Standards were developed based on available guidelines in use at the start of 2012 covering case mix and dosimetry. Further questions were included to reflect areas of anticipated change with the implementation of the 2012 guidelines. Audit findings were compared with similar audits of practice in Europe, the USA and Latin America. RESULTS: Forty-nine of 59 cancer centres submitted data. Twenty-nine centres reported carrying out prostate brachytherapy; of these, 25 (86%) provided data regarding the number of implants, staffing, dosimetry, medication and anaesthesia and follow-up. Audit standards achieved excellent compliance in most areas, although were low in post-implant dosimetry and in post-implant scanning at 30 days. CONCLUSION: This audit provides a comprehensive picture of prostate brachytherapy in the UK in 2012. Patterns of care of prostate brachytherapy are similar to practice in the USA and Europe. The number of prostate brachytherapy implants carried out in the UK has grown significantly since a previous RCR audit in 2005 and it is important that centres maintain minimum numbers of cases to ensure that experience can be maintained and compliance to guidelines achieved.

RESUMEN

Ocular dominance columns (ODCs) exist in many primates and carnivores, but it is believed that they do not exist in rodents. Using a combination of transneuronal tracing, in situ hybridization for Zif268 and electrophysiological recordings, we show that inputs from both eyes are largely segregated in the binocular region of V1 in Long Evans rats. We also show that, interposed between this binocular region and the lateral border of V1, there lies a strip of cortex that is strongly dominated by the contralateral eye. Finally, we show that callosal connections colocalize primarily with ipsilateral eye domains in the binocular region and with contralateral eye input in the lateral cortical strip, mirroring the relationship between patchy callosal connections and specific sets of ODCs described previously in the cat. Our results suggest that development of cortical modular architecture is more conserved among rodents, carnivores, and primates than previously thought.
