RESUMO

BACKGROUND: Whole-of-school programs have demonstrated success in improving student physical activity levels, but few have progressed beyond efficacy testing to implementation at-scale. The purpose of our study was to evaluate the scale-up of the 'Internet-based Professional Learning to help teachers promote Activity in Youth' (iPLAY) intervention in primary schools using the RE-AIM framework. METHODS: We conducted a type 3 hybrid implementation-effectiveness study and collected data between April 2016 and June 2021, in New South Wales (NSW), Australia. RE-AIM was operationalised as: (i) Reach: Number and representativeness of students exposed to iPLAY; (ii) Effectiveness: Impact of iPLAY in a sub-sample of students (n = 5,959); (iii) Adoption: Number and representativeness of schools that received iPLAY; (iv) Implementation: Extent to which the three curricular and three non-curricular components of iPLAY were delivered as intended; (v) Maintenance: Extent to which iPLAY was sustained in schools. We conducted 43 semi-structured interviews with teachers (n = 14), leaders (n = 19), and principals (n = 10) from 18 schools (11 from urban and 7 from rural locations) to determine program maintenance. RESULTS: Reach: iPLAY reached ~ 31,000 students from a variety of socio-economic strata (35% of students were in the bottom quartile, almost half in the middle two quartiles, and 20% in the top quartile). EFFECTIVENESS: We observed small positive intervention effects for enjoyment of PE/sport (0.12 units, 95% CI: 0.05 to 0.20, d = 0.17), perceptions of need support from teachers (0.26 units, 95% CI: 0.16 to 0.53, d = 0.40), physical activity participation (0.28 units, 95% CI: 0.10 to 0.47, d = 0.14), and subjective well-being (0.82 units, 95% CI: 0.32 to 1.32, d = 0.12) at 24-months. Adoption: 115 schools received iPLAY. IMPLEMENTATION: Most schools implemented the curricular (59%) and non-curricular (55%) strategies as intended. Maintenance: Based on our qualitative data, changes in teacher practices and school culture resulting from iPLAY were sustained. CONCLUSIONS: iPLAY had extensive reach and adoption in NSW primary schools. Most of the schools implemented iPLAY as intended and effectiveness data suggest the positive effects observed in our cluster RCT were sustained when the intervention was delivered at-scale. TRIAL REGISTRATION: ACTRN12621001132831.

RESUMO

In order to continue to deliver outstanding medical care on the battlefield, the UK Defence Medical Services must continue to adapt, overcome and actively embrace change. One potential area is the rapid proliferation and sophistication of automated and remote systems such as unmanned aerial vehicles (UAVs). UAVs are already used to deliver blood to remote military locations in Afghanistan and defibrillators to those that need them in the USA and Sweden. An area of future opportunity would be to facilitate rapid evacuation of wounded personnel from high intensity, high threat, remote and austere areas directly to specialist care. Such a capability would reduce threat to human life while allowing rapid extraction of casualties from high risk or inaccessible environments straight back to Role 3 care, all of which in these situations is either not possible or carries too much risk using conventional aerial assets. The article aims to highlight a potential future capability, stimulate debate and reflection, all of which is essential for innovation and future organisational development. The potential uses and benefits of UAVs are highlighted including both the challenges and rewards of utilising UAVs for casualty evacuation. Key benefits are reduced risk to human life, cost, ability to insert into areas conventional aircraft cannot and the rapidity of transfer. Challenges are likely to be airspace management, decisions on appropriate level of care to deliver during transit and ultimately user acceptability. The article also highlights that in order to maximise our ability to exploit new technologies, all arms and trades within the military must be involved in collective research and development. Furthermore, sensible corroboration with private companies will further enhance our ability to acquire products that best serve our needs.

RESUMO

AIM: To describe the mechanisms, burden of injury, inpatient management and rehabilitation requirements of wounded military personnel at the UK Role 4 (R4) facility within the first 12 months following cessation of combat operations in Afghanistan. METHODS: All aeromedical evacuations were recorded prospectively between October 2014 and October 2015. Demographic, logistical and clinical data were derived manually from referring medical unit and patient movement requests in addition to host nation and R4 medical records. RESULTS: Ninety-five patients were repatriated to R4 following traumatic injury: 98.9% (n=94) were male, and median age was 27 years (IQR 25-36 years). The most common mechanisms of injury (MOIs) were sports 26.3% (n=25), falls <2 m 11.6% (n=11) and road traffic collisions 9.8% (n=9). The most common anatomical regions of injury were isolated lower limb 24.1% (n=22), isolated hand 20.0% (n=19) and polytrauma 14.7% (n=14). Median Injury Severity Score was 4 (IQR 4-9), mean 8 (range 1-41). Eleven patients (11.6%) were discharged to rehabilitation units, of whom 7 (63.6%) required neurorehabilitation. CONCLUSION: Although service personnel sustain civilian-type injuries, the specific rehabilitation goals and shift in the acute rehabilitation requirements for military personnel must be considered in the absence of enduring combat operations. It is notable that permanent medical downgrading secondary to trauma still occurs outside of warfare. The colocation of civilian major trauma services and R4 has ensured a mutually beneficial partnership that contributes to institutional memory and improves the coordination of patient pathways. The importance of relevant resource allocation, training, support and logistical considerations remain, even during the current scale of military activity overseas.

RESUMO

BACKGROUND: The signal transducer and activator of transcription-4 (STAT4/Stat4) is a transcription factor known to convey signals from interleukin-12, interleukin-23, and interferon-alpha/beta to the nucleus, resulting in activation of dendritic cells, T-helper cell differentiation and production of interferon-gamma. OBJECTIVE: To demonstrate a novel role for STAT4 in cell mitosis. RESULTS: Phosphoserine STAT4 (pSerSTAT4) is increased in cells undergoing mitosis and is distributed throughout the cytoplasm during this stage of the cell cycle, whilst phosphotyrosine STAT4 (pTyrSTAT4) is confined to the chromosomal compartment. This distinct pattern of pSerSTAT4 during mitosis is seen in vitro in human keratinocytes and in other cell types. This is also present in vivo in cells undergoing mitosis in normal skin, psoriasis and squamous cell carcinoma. Inhibition of STAT4 phosphorylation by lisofylline and depletion of STAT4 by RNA interference results in a delay in progression of mitosis and leads to a reduction in cells completing cytokinesis. CONCLUSION: Our data demonstrate that STAT4 plays a role in enabling the normal and timely division of cells undergoing mitosis.

RESUMO

BACKGROUND: Fatigue in military operations leads to safety and operational problems due to a decrease in alertness and performance. The primary method of counteracting the effects of sleep deprivation is to increase nightly sleep time, which in operational situations is not always feasible. History has taught us that surgeons and surgical teams are finite resources that cannot operate on patients indefinitely. METHODS: A systematic review was conducted using the search terms 'sleep' and 'deprivation' examining the impact of sleep deprivation on cognitive performance in military surgical teams. Studies examining outcomes on intensive care patients and subjects with comorbidities were not addressed in this review. RESULTS: Sleep deprivation in any 'out-of-hours' surgery has a significant impact on overall morbidity and mortality. Sleep deprivation in surgeons and surgical trainees negatively impacts cognitive performance and puts their own and patients' health at risk. All published research lacks consensus when defining 'sleep deprivation' and 'rested' states. It is recognised that it would be unethical to conduct a well-designed randomised controlled trial, to determine the effects of fatigue on performance in surgery; however, there is a paucity between surrogate markers and applying simulated results to actual clinical performance. This requires further research. Recommended methods of combating fatigue include: prophylactically 'sleep-banking' prior to known periods of sleep deprivation, napping, use of stimulant or alerting substances such as modafinil, coordinated work schedules to reduce circadian desynchronisation and regular breaks with enforced rest periods. CONCLUSIONS: A forward surgical team will become combat-ineffective after 48 hours of continuous operations. This systematic review recommends implementing on-call periods of no more than 12 hours in duration, with adequate rest periods every 24 hours. Drug therapies and sleep banking may, in the short term, prevent negative effects of acute sleep deprivation.

RESUMO

INTRODUCTION: Military elements increasingly operate in small teams in remote areas with no immediate blood product support. Planners and operators may endorse collection of fresh whole blood from pretested donors in emergency situations. The biggest risk of transfusion is the accidental use of ABO incompatible blood which can be fatal. The risk may be mitigated by using only group O LOw (OLO) titre donors with plasma containing low levels of the naturally occurring antibody to group A and B red cells. This paper reviews the ABO blood group distribution in potential blood donors from a high readiness UK medical regiment and explores the feasibility of using only group OLO donors in small teams. METHODS: A retrospective review of routine volunteer blood donor samples was undertaken at 6 monthly intervals during a 2-year period. Personnel were tested in groups when available during training to create multiple donor panels to simulate small teams. RESULTS: 206 donation samples were collected from 157 potential donors. All donors were acceptable based on the lifestyle questionnaire, serology and microbiology screen. Of the 206 samples reviewed, 85 (41%) were group O (D pos and D neg). 14 group O (16.5%) were shown to have high titre of anti-A or B. Therefore, 71, that is, 34% overall were suitable as OLO donors. The donor panel size varied from 15 to 44. The absolute number of OLO donors in each panel ranged from 4 to 17 and the number of O neg donors was 0-3. CONCLUSION: A third of samples were suitable as OLO donors; however, there were insufficient 'universal' donors within smaller subgroups (<10). In this situation, we recommend the careful use of both group O and group A donors or the use of a buddy-buddy blood group matrix.

RESUMO

INTRODUCTION: This paper describes the clinical governance, training, equipment and infrastructure developed to enable a UK Role 1 medical team to deliver forward transfusion in Southern Afghanistan. The aim was to explore the utility and feasibility of forward blood transfusion by a Role 1 medical team in an austere military environment. METHODS: An audit of prospectively collected transfusion regulatory and cold chain data using standard-issue equipment and governance systems. TempIT tags were read before and after each mission to record blood storage temperature. Two years' data were analysed to review the use of blood products, cold chain compliance and equipment issues. RESULTS: Over 24 months, blood products were carried on over 1000 mission hours. Two clinical cases required transfusion and were successfully resuscitated. The team was able to correctly transport, store and deploy red cells and plasma on missions using standard Ministry of Defence (MOD) issue equipment. There were seven cold chain failures, all of which were addressed locally. Current cold chain and diagnostic equipment would require further optimisation for use at Role 1. CONCLUSIONS: An isolated Role 1 medical team can safely deliver blood transfusion on vehicle, helicopter or foot patrols. The transport and storage of blood created a large logistical burden for a relatively small clinical output. However, with further developments, this capability may have utility in contingency operations especially for isolated teams.

RESUMO

Protein kinase C (PKC) is a family of serine/threonine tyrosine kinases that regulate many cellular processes including division, proliferation, survival, anoikis and polarity. PKC is abundant in many human cancers and aberrant PKC signalling has been demonstrated in cancer models. On this basis, PKC has become an attractive target for small molecule inhibition within oncology drug development programmes. Sarcoma is a heterogeneous group of mesenchymal malignancies. Due to their relative insensitivity to conventional chemotherapies and the increasing recognition of the driving molecular events of sarcomagenesis, sarcoma provides an excellent platform to test novel therapeutics. In this review we provide a structure-function overview of the PKC family, the rationale for targeting these kinases in sarcoma and the state of play with regard to PKC inhibition in the clinic.

RESUMO

As a result of the COVID-19 pandemic, Long COVID (LC) is now prevalent in many countries. Little evidence exists regarding how this chronic condition should be treated, but guidelines suggest for most people it can be managed symptomatically in primary care. The Lightning Process is a trademarked positive psychology focused self-management programme which has shown to be effective in reducing fatigue and accompanying symptoms in other chronic conditions including Chronic Fatigue Syndrome/Myalgic Encephalomyelitis. Here we outline its novel application to two patients with LC who both reported improvements in fatigue and a range of physical and emotional symptoms post-treatment and at 3 months follow-up.

RESUMO

Haemosporidian parasites in the genus Plasmodium were recently detected through molecular screening in the Galapagos Penguin (Spheniscus mendiculus). We summarized results of an archipelago-wide screen of 3726 endemic birds representing 22 species for Plasmodium spp. through a combination of molecular and microscopy techniques. Three additional Plasmodium lineages were present in Galapagos. Lineage A-infected penguins, Yellow Warblers (Setophaga petechia aureola), and one Medium Ground Finch (Geospiza fortis) and was detected at multiple sites in multiple years [corrected]. The other 3 lineages were each detected at one site and at one time; apparently, they were transient infections of parasites not established on the archipelago. No gametocytes were found in blood smears of infected individuals; thus, endemic Galapagos birds may be dead-end hosts for these Plasmodium lineages. Determining when and how parasites and pathogens arrive in Galapagos is key to developing conservation strategies to prevent and mitigate the effects of introduced diseases. To assess the potential for Plasmodium parasites to arrive via migratory birds, we analyzed blood samples from 438 North American breeding Bobolinks (Dolichonyx oryzivorus), the only songbird that regularly migrates through Galapagos. Two of the ephemeral Plasmodium lineages (B and C) found in Galapagos birds matched parasite sequences from Bobolinks. Although this is not confirmation that Bobolinks are responsible for introducing these lineages, evidence points to higher potential arrival rates of avian pathogens than previously thought.

RESUMO

BACKGROUND: Improvised explosive device (IED) yields in Afghanistan have increased resulting in more proximal injuries. The injury severity score (ISS) is an anatomic aggregate score of the three most severely injured anatomical areas but does not accurately predict severity in IED related pelvi-perineal trauma patients. A scoring system based on abbreviated injury score (AIS) was developed to reflect the severity of these injuries in order to better understand risk factors, develop a tool for future audit and improve performance. METHOD: Using standard AIS descriptors, injury scales were constructed for the pelvis (1, minor to 6, maximal). The perineum was divided into anterior and posterior zones as relevant to injury patterns and blast direction with each soft tissue structure being allocated a score from its own severity scale. A cumulative score, from 1 to 36 for soft tissue, or a maximum of 42 if a pelvic fracture was involved, was created for all structures injured in the anterior and posterior zones. RESULTS: Using this new scoring system, 77% of patients survived with a pelvi-perineal trauma score (PPTS) below 5. There was a significant increase in mortality, number of pelvic fractures and amputations with increase in score when comparing the first group (score 1-5) to the second group (score 6-10). For scores between 6 and 16 survival was 42% and 22% for scores between 17 and 21. In our cohort of 62 survivors, 1 patient with an IED related pelvi-perineal injury had a 'theoretically un-survivable' maximal ISS of 75 and survived, whereas there were no survivors with a PPTS greater than 22 but this group had no-one with an ISS of 75 suggesting ISS is not an accurate reflection of the true severity of pelvi-perineal blast injury. CONCLUSIONS: This scoring system is the initial part of a more complex logistic regression model that will contribute towards a unique trauma scoring system to aid surgical teams in predicting fluid requirements and operative timelines. In austere environments, it may also help to prevent futile resuscitations. Better correlation between measurement of severity and outcome would aid performance improvement monitoring. In the longer term it will also allow benchmarking of current survival rates and comparisons in the future.

RESUMO

INTRODUCTION: Since 2012, the Damage Control Orthopaedic Trauma Skills course (DCOTS) has trained more than 250 surgeons in the principles and practice of damage control orthopaedics and early appropriate care. This Royal College of Surgeons of England (RCS England) course takes place at the RCS England Partner cadaver laboratory at Brighton and Sussex Medical School. Trauma is a leading cause of morbidity and mortality in the UK, and the course has tried to pass on the lessons of war and conflict from its military faculty and hard-won lessons of "developed world" trauma from its experienced civilian faculty. METHODS: Participating surgeons were invited to score their self-reported confidence before attending the DCOTS course, immediately afterwards and again 6 months later. A modified four-point Likert scale was used, with responses from 1 = No Confidence to 4 = Very Confident. Damage control resuscitation principles with damage control surgery showed the greatest retained increase at 6 months - 100% - which is extremely satisfying. RESULTS: Self-reported confidence in pelvic external fixation was initially 93% dropping to 85%, which is also considered good to excellent. For pelvic packing, confidence was 90% at the end of the course, up from 19% precourse. This dropped to 62%, which was still considered good but low for the high standards of the course. This may relate to UK trainees' lack of familiarity with the concept. CONCLUSIONS: Three of the main skills taught on the DCOTS are effectively retained at 6 months post course.

RESUMO

Anterior cruciate ligament (ACL) rupture is a common injury that affects young, active individuals, normally managed with reconstruction in this age group. Current UK Armed Forces policy precludes prospective applicants from joining with an anterior cruciate ligament reconstruction (ACLR). This isdue to the perceived risk of premature osteoarthritis (OA), graft rupture or clinical failure, all of which could make the service person medically non-deployable.The most recent evidence shows that an ACL rupture without associated significant meniscal or osteochondral defect has a similar likelihood of developing OA as to that of the uninjured knee after reconstruction at 20 years postoperatively.Applicants should be considered for service following an ACL rupture without significant concurrent meniscal or osteochondral defect who have undergone ACLR and 18 months of rehabilitation. We recommend these applicants to be graded P2 Medically Fully Deployable (MFD) as per the Joint Service Publication (JSP) guidance for service personnel who undergo ACLR.

RESUMO

BACKGROUND: 'Non-compressible' haemorrhage is the leading cause of preventable battlefield death, often requiring surgical or radiological intervention, which is precluded in the pre-hospital environment. One-fifth of such bleeds are junctional and therefore potentially survivable. We examine the use of the Abdominal Aortic Junctional Tourniquet - Stabilized (AAJTS) among UK Combat Medical Technicians (CMTs) as a device to control junctional haemorrhage with external compression of the abdominal aorta-compression of junctional haemorrhage previously considered 'non-compressible.' This follows animal studies showing that the AAJTS achieves control of haemorrhage and improves physiological parameters. METHODS: CMTs were selected and applied the AAJTS to each other following a 1-hour training package. A consultant radiologist-operated hand-held ultrasound monitored flow changes in the subjects' common femoral artery. CMTs were then surveyed for their opinions as to utility and function. RESULTS: 21 CMTs were screened and 17 CMTs participated with 34 total applications (16 day and 18 low-light). 27/34 (79%) achieved a successful application. The median application time was 75 s in daylight and 57 s in low-light conditions. There was no significant difference in Body Mass Index (p=0.23), median systolic blood pressure (p=0.19), nor class of CMT (p=0.10) between successful and unsuccessful applications. Higher systolic blood pressure was associated with longer application times (p=0.03). Users deemed the device easy to use (median score 4.4 on a 5-point Likert scale). CONCLUSION: CMTs can use AAJTS successfully after a 1-hour training session in the majority of applications. Application was successful in both daylight and low-light conditions. Self-reported usability ratings were high.

RESUMO

BACKGROUND: An augmented Broström repair with nonabsorbable suture tape has demonstrated strength and stiffness more similar to the native anterior talofibular ligament (ATFL) compared to Broström repair alone at the time of repair in cadaveric models for the treatment of lateral ankle instability. The study purpose was to compare minimum 2-year patient-reported outcomes (PROs) following treatment of ATFL injuries with Broström repair with vs without suture tape augmentation. METHODS: Between 2009 and 2018, patients >18 years old who underwent primary surgical treatment for an ATFL injury with either a Broström repair alone (BR Cohort) or Broström repair with suture tape augmentation (BR-ST Cohort) were identified. Demographic data and PROs, including Foot and Ankle Ability Measure (FAAM) with activities of daily living (ADL) and sport subscales, 12-Item Short Form Health Survey (SF-12), Tegner Activity Scale, and patient satisfaction with surgical outcome, were compared between groups, and proportional odds ordinal logistic regression was used. RESULTS: Ninety-one of 102 eligible patients were available for follow-up at median 5 years. The BR cohort had 50 of 53 patients (94%) completed follow-up at a median of 7 years. The BR-ST cohort had 41 of 49 (84%) complete follow-up at a median of 5 years. There was no significant difference in median postoperative FAAM ADL (98% vs 98%, P = .67), FAAM sport (88% vs 91%, P = .43), SF-12 PCS (55 vs 54, P = .93), Tegner score (5 vs 5, P = .64), or patient satisfaction (9 vs 9, P = .82). There was significantly higher SF-12 MCS (55.7 vs 57.6, P = .02) in the BR-ST group. Eight patients underwent subsequent ipsilateral ankle surgery, of which one patient (BR-ST group) was revised for recurrent lateral ankle instability. CONCLUSION: At median 5 years, patients treated for ATFL injury of the lateral ankle with Broström repair with suture tape augmentation demonstrated similar patient-reported outcomes to those treated with Broström repair alone. LEVEL OF EVIDENCE: Level II, retrospective cohort study.

RESUMO

The quantitative consistency of nucleon transfer reactions as a probe of the occupancy of valence orbits in nuclei is tested. Neutron-adding, neutron-removal, and proton-adding transfer reactions were measured on the four stable even Ni isotopes, with particular attention to the cross section determinations. The data were analyzed consistently in terms of the distorted wave Born approximation to yield spectroscopic factors. Valence-orbit occupancies were extracted, utilizing the Macfarlane-French sum rules. The deduced occupancies are consistent with the changing number of valence neutrons, as are the vacancies for protons, both at the level of <5%. While there has been some debate regarding the true "observability" of spectroscopic factors, the present results indicate that empirically they yield self-consistent results.

RESUMO

The faunas associated with oceanic islands provide exceptional examples with which to examine the dispersal abilities of different taxa and test the relative contribution of selective and neutral processes in evolution. We examine the patterns of recent differentiation and the relative roles of gene flow and selection in genetic and morphological variation in the yellow warbler (Dendroica petechia aureola) from the Galápagos and Cocos Islands. Our analyses suggest aureola diverged from Central American lineages colonizing the Galápagos and Cocos Islands recently, likely less than 300 000 years ago. Within the Galápagos, patterns of genetic variation in microsatellite and mitochondrial markers suggest early stages of diversification. No intra-island patterns of morphological variation were found, even across steep ecological gradients, suggesting that either (i) high levels of gene flow may be homogenizing the effects of selection, (ii) populations may not have had enough time to accumulate the differences in morphological traits, or (iii) yellow warblers show lower levels of 'evolvability' than some other Galápagos species. By examining genetic data and morphological variation, our results provide new insight into the microevolutionary processes driving the patterns of variation.

RESUMO

BACKGROUND: We describe a minimally invasive, image-guided technique for obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome complicated by tubo-ovarian abscess (TOA). CASE: A 15-year-old female adolescent with OHVIRA syndrome presented with TOA. Magnetic resonance imaging of the abdomen/pelvis showed a loculated pelvic mass and fluid collection near the obstructed left hemivagina. Tissue quality and ill-defined surgical planes prevented surgical excision. A transabdominal drain was placed via laparoscopic port by Interventional Radiology. She later underwent transvaginal and transabdominal drain placement into the hemivaginal collection using computed tomography and ultrasound guidance, allowing for surgical excision of the vaginal septum, drainage and excision of the TOA, and neosalpingostomy. SUMMARY AND CONCLUSION: Because of the anatomic complexity in OHVIRA syndrome, preoperative minimally invasive techniques with Interventional Radiology collaboration can assist intraoperative anatomic navigation for successful surgical treatment.

RESUMO

INTRODUCTION: The most impactful resolutions of the Patient Protection and Affordable Care Act (ACA) took effect on January 1, 2014. The clinical and economic effects are widely experienced by orthopaedic surgeons, but are not well quantified. We proposed to evaluate the effect of the ACA on the timing of MRI for knee pathology before and after implementation of the legislation. METHODS: We conducted a retrospective analysis of all knee MRIs done at our institution from 2011 to 2016 (3 years before and after ACA implementation). The MRI completion time was calculated by comparing the dates of initial clinical evaluation and MRI completion. The groups were subdivided based on insurance payer status (Medicare, Medicaid, and commercial payers). The cohorts were compared to determine differences in average completion time and completion rates at time intervals from initial clinic visit before and after ACA implementation. RESULTS: MRI scans of 5,543 knees were included, 3,157 (57%) before ACA implementation and 2,386 (43%) after. There was a 5.6% increase in Medicaid cohort representation after ACA implementation. Patients waited 14 days longer for MRIs after ACA implementation (116 versus 102 days). There were increased completion times for patients in the commercial payer (113 versus 100 days) and Medicaid (131 versus 96 days) groups. Fewer patients had received MRI after ACA implementation within 2, 6, and 12 weeks of their initial clinic visits. DISCUSSION: The time between initial clinical evaluation and MRI scan completion for knee pathology markedly increased after ACA implementation, particularly in the commercial payer and Medicaid cohorts. Additional studies are needed to determine the effect of longer wait times on patient satisfaction, delayed treatment, and increased morbidity. As healthcare policy changes continue, their effects on orthopaedic patients and providers should be closely scrutinized. LEVEL OF EVIDENCE: Level III-Retrospective cohort study.

RESUMO

AIMS: Pregabalin (PGB) was licensed in Europe as an add-on antiepileptic drug (AED) for the treatment of partial-onset seizures in 2004. This audit assessed the response to adjunctive PGB in patients with uncontrolled seizures. METHODS: PGB was titrated in 135 patients [73 men; 62 women, aged 18-76 (median 44 years) until one of the following occurred: ≥ 6 months' seizure freedom, ≥ 50% or < 50% seizure reduction over 6 months; PGB withdrawal because of adverse effects, lack of efficacy or both. RESULTS: Of the 135 patients, 14 (10.4%) became seizure-free for ≥ 6 months (median PGB dose 300 mg/day; range 75-600 mg). A ≥ 50% seizure reduction occurred in 33 (24.4%) patients; 20 (14.8%) had < 50% reduction. PGB was withdrawn in 68 (50.4%) (40 adverse effects, seven lack of efficacy and 21 both). Commonest problems resulting in withdrawal were sedation (n = 18), weight gain (n = 14) and ataxia (n = 9). There was a positive correlation between increasing dose and weight gain (r = 0.42, P = 0.045). CONCLUSIONS: Add-on PGB benefited 50% of patients, but only 10% achieved 6 months' seizure freedom. Adverse effects, most commonly sedation, dose-related weight gain and ataxia, led to drug discontinuation by 45%. Prospective audits of novel AEDs are a useful adjunct to randomized, controlled trials in managing epilepsy.
