Resumen

Introduction. The process of synthesizing scientific evidence and translating elaborate scientific research findings into recommendations for clinical practice is one of the most complex and significant initiatives in health care. In connection with the increasing number of recommendations, previously unformalised elements such as the process of consensus decision-making require developing a methodological approach. The use of consensus methods serves to reduce the impact of psychosocial factors in the formulation of recommendations and to increase the degree of process transparency. The aim of the publication is to present formal methods of achieving consensus used in the process of developing clinical practice guidelines. Materials and methods. The review focuses on results of reports analyzing the procedure and methods of developing clinical recommendations, with particular emphasis on the identification of consensus methods. Results. Many international and national organizations and institutions develop recommendations or adapt guidelines developed by others. They use both informal and formal instruments to deal with divergent expert opinions. The most popular formal methods of achieving consensus identified in the review are the Delphi method, the nominal group technique, the RAND/UCLA method, the consensus conference, and the combinations of individual approaches. Formal methods have been shown to lead to less biased and more reliable recommendations. Regardless of the method used, the guidelines should clearly define the quorum and document the process of agreeing a common standpoint on recommendations, guidelines and recommendations. Conclusions. Clinical guidelines have become an important tool influencing clinical practice. The participation of many experts representing the opinions and interests of different groups makes it necessary to apply a methodological and structured approach so that all participants have the opportunity to voice their opinion and to ensure process transparency, deal with misunderstandings and achieve a consensual position. The consensus methods allow to provide a wide range of stakeholders clinicians, policy makers, patients – with agreed rules of conduct in a given topic. The formal consensus methods and recommendations based on these methods combine scientific evidence with the practice and experience of experts.

Resumen

In order to overcome the drawbacks of the convergence time boundary dependent on tuning parameters in existing finite/fixed-time cooperative guidance law, this paper presents a three-dimensional prescribed-time pinning group cooperative guidance scheme that ensures multiple unpowered missiles to intercept multiple stationary targets. Firstly, combining a prescribed-time scaling function with pinning group consensus theory, the prescribed-time consensus-based cooperative guidance law is proposed. Secondly, the prescribed-time convergence of the proposed pinning group consensus-based cooperative guidance law proves that the convergence can be achieved at a specified time, regardless of initial conditions and parameters. Furthermore, the design steps including two stages of the proposed guidance law are given for engineering application. Extensive simulations are carried out in three cases to verify the properties. Simulation results show the effectiveness and superiority of the proposed prescribed-time consensus-based cooperative guidance scheme.

Resumen

Abstract Two approaches are developed and tested to improve the unweighted position consensus for 96-, 108-, and 120-h tropical cyclone track guidance in the western North Pacific. A weighted position guidance technique uses a weighting factor for each model that is inversely proportional to how far the 60-, 66-, and 72-h positions of that model are from the corresponding positions of the 11-member position consensus. The weighted position consensus of 96-, 108-, and 120-h track errors for a sample of 24 storms during the 2006 season are consistently smaller than for the unweighted position consensus. In the second approach, a weighted motion vector consensus is developed that uses the same weighting factors as in the weighted position consensus, except that the weights are applied to 12-h motion vectors between 84 and 120 h. This weighted motion vector consensus has substantially smaller errors than the unweighted position consensus, and results in smoother tracks when one or more of the model tracks drops out of the consensus. It is proposed that the weighted motion vector consensus would provide improved guidance for the 96-, 108-, and 120-h tropical cyclone track forecasts.

Resumen

BackgroundRett syndrome (RTT) is a severe neurodevelopmental disorder with complex medical comorbidities extending beyond the nervous system requiring the attention of health professionals. There is no peer-reviewed, consensus-based therapeutic guidance to care in RTT. The objective was to provide consensus on guidance of best practice for addressing these concerns.MethodsInformed by the literature and using a modified Delphi approach, a consensus process was used to develop guidance for care in RTT by health professionals.ResultsTypical RTT presents early in childhood in a clinically recognisable fashion. Multisystem comorbidities evolve throughout the lifespan requiring coordination of care between primary care and often multiple subspecialty providers. To assist health professionals and families in seeking best practice, a checklist and detailed references for guidance were developed by consensus.ConclusionsThe overall multisystem issues of RTT require primary care providers and other health professionals to manage complex medical comorbidities within the context of the whole individual and family. Given the median life expectancy well into the sixth decade, guidance is provided to health professionals to achieve current best possible outcomes for these special-needs individuals.

Resumen

The need for equitable access to high-quality preschool has recently gained unprecedented attention. As states and districts strive to expand access while promoting quality, curriculum quality has emerged as a critical component of preschool programs that promote young children’s learning. Yet many educators make curricular decisions with insufficient guidance on what constitutes curricular quality. Indeed, deep divisions in the field are evident regarding how to define quality in preschool curricula. Jeanne L. Reid and Sharon Lynn Kagan explore the areas of consensus and disagreement among early education leaders. They argue that — using guidance from a study at the National Academies of Sciences, Engineering, and Medicine and drawing from international models of curriculum frameworks — the field can move toward consensus on what constitutes a high-quality curriculum and thus help to fulfill the promise of equitable access to high-quality preschool.

Resumen

Background: Public health emergencies require rapid responses from experts. Differing viewpoints are common in science, however, “mixed messaging” of varied perspectives can undermine credibility of experts; reduce trust in guidance; and act as a barrier to changing public health behaviours. Collation of a unified voice for effective knowledge creation and translation can be challenging. This work aimed to create a method for rapid psychologically-informed expert guidance during the COVID-19 response. Method: TRICE (Template for Rapid Iterative Consensus of Experts) brings structure, peer-review and consensus to the rapid generation of expert advice. It was developed and trialled with 15 core members of the British Psychological Society COVID-19 Behavioural Science and Disease Prevention Taskforce. Results: Using TRICE; we have produced 18 peer-reviewed COVID-19 guidance documents; based on rapid systematic reviews; co-created by experts in behavioural science and public health; taking 4–156 days to produce; with approximately 18 experts and a median of 7 drafts per output. We provide worked-examples and key considerations; including a shared ethos and theoretical/methodological framework; in this case; the Behaviour Change Wheel and COM-B. Conclusion: TRICE extends existing consensus methodologies and has supported public health collaboration; co-creation of guidance and translation of behavioural science to practice through explicit processes in generating expert advice for public health emergencies.

Resumen

Various individual tree appraisal methods emerged during the first half of the 20th century. Development of North American industry consensus methods was undertaken in 1947. These methods have been refined and elaborated, and additional guidance has been provided in subsequent revisions. Appraisers and appraisal users, however, are not always aware of the most current methods and guidance and may, unknowingly, rely on outdated versions. The purpose of this paper is to provide an accurate and quick reference to the chronology of North American industry-wide consensus methods and guidance for tree and plant appraisal. The differences among methods, guidance, and standards are also explained.

Resumen

This paper proposes a consensus-based guidance methodology for multiple air vehicles to arrive at the same spot cooperatively. First, based on the Lyapunov stability theory, a guidance law with only one control parameter is proposed, and the exact expression of total flight time can be obtained with a control parameter equal to one. Then, a two-step guidance scheme, which can achieve a finite-time consensus of the flight time, is built upon the Lyapunov-based guidance law. In the first step, on account of the information exchange between the air vehicles through an undirected and connected communication topology, a time-varying control parameter is designed to reduce the disparities of the flight time. After the consensus of the flight time, the control parameter will remain constant at one, and simultaneous arrival can be achieved. Besides, the guidance strategy is applied in a leader-follower case that one of the vehicles cannot receive information from the others and acts as the leader. The effectiveness of the proposed method is demonstrated with simulations.

Resumen

The initial conditions of the cooperative terminal guidance law, which are the terminal conditions of the cooperative midcourse guidance, have a greater impact on its cooperation and guidance precision, so it is worthy of investigating the cooperative midcourse guidance. In addition, the problem of communication delay between the network nodes is inevitable and has a greater impact on the cooperative guidance law. To solve the above problems, a novel distributed cooperative midcourse guidance (DCMG) law with communication delay is proposed by combining the cooperative term with a distributed consensus protocol including communication delay under the directed communication topology. Firstly, a DCMG law with communication delay is designed by combining the trajectory shaping guidance with the distributed protocol including communication delay under the directed communication topology; secondly, the consensus of the proposed DCMG law with communication delay under the directed graph is proved; finally, the effectiveness and superiority of the proposed DCMG law are verified by numerical simulations.

Resumen

Considering three-dimensional formation control for multiple unmanned aerial vehicles, this paper proposes a second-order consensus strategy by utilizing the position and velocity coordinate variables. To maintain the specified geometric configuration, a cooperative guidance algorithm and a cooperative control algorithm are proposed together to manage the position and attitude, respectively. The cooperative guidance law, which is designed as a second-order consensus algorithm, provides the desired pitch rate, heading rate and acceleration. In addition, a synchronization technology is put forward to reduce the influence of the measurement errors for the cooperative guidance law. The cooperative control law, regarding the output of the cooperative guidance law as its input, is designed by deducing the state-space expression of both the longitudinal and lateral motions. The formation stability is analyzed to give a sufficient and necessary condition. Finally, the simulations for the three-dimensional formation control demonstrate the feasibility and effectiveness of the second-order consensus strategy.

Resumen

Abstract Forecasting tropical storm intensities is a very challenging issue. In recent years, dynamical models have improved considerably. However, for intensity forecasts more improvement is necessary. Dynamical models have different kinds of biases. Considering a multimodel consensus could eliminate some of the biases resulting in improved intensity forecasts as compared to the individual models. Apart from the ensemble mean, the construction of multimodel consensuses has always contributed to somewhat improved forecasts. The Florida State University (FSU) multimodel superensemble is one that, over the years, has systematically provided improved forecasts for hurricanes, numerical weather prediction, and seasonal climate forecasts. The present study considers an artificial neural network (ANN), based on biological principles, for the construction of a multimodel ensemble. ANN has been used for constructing multimodel consensus forecasts for tropical cyclone intensities. This study uses the generalized regression neural network (GRNN) method for the construction of consensus intensity forecasts for the Atlantic basin. Hurricane seasons 2012–16 are considered. Results show that with only five input models improved guidance for tropical storm intensities may be obtained. The consensus using GRNN mostly outperforms all the models included in the study and the ensemble mean. Forecast errors at the longer forecast leads are considerably less for this multimodel superensemble based on the generalized regression neural network. The skill and correlations of different models along with the developed consensus are provided in our analysis. Results suggest that this consensus forecast may be used for operational guidance and for planning and emergency evacuation management. Possibilities for future improvements of the consensus based on new advances in statistical algorithms are also indicated.

Resumen

ObjectiveTo identify evidence on the reporting quality of consensus methodology and to select potential checklist items for the ACcurate COnsensus Reporting Document (ACCORD) project to develop a consensus reporting guideline.DesignSystematic review.Data sourcesEmbase, MEDLINE, Web of Science, PubMed, Cochrane Library, Emcare, Academic Search Premier and PsycINFO from inception until 7 January 2022.Eligibility criteriaStudies, reviews and published guidance addressing the reporting quality of consensus methodology for improvement of health outcomes in biomedicine or clinical practice. Reports of studies using or describing consensus methods but not commenting on their reporting quality were excluded. No language restrictions were applied.Data extraction and synthesisScreening and data extraction of eligible studies were carried out independently by two authors. Reporting quality items addressed by the studies were synthesised narratively.ResultsEighteen studies were included: five systematic reviews, four narrative reviews, three research papers, three conference abstracts, two research guidance papers and one protocol. The majority of studies indicated that the quality of reporting of consensus methodology could be improved. Commonly addressed items were: consensus panel composition; definition of consensus and the threshold for achieving consensus. Items least addressed were: public patient involvement (PPI); the role of the steering committee, chair, cochair; conflict of interest of panellists and funding. Data extracted from included studies revealed additional items that were not captured in the data extraction form such as justification of deviation from the protocol or incentives to encourage panellist response.ConclusionThe results of this systematic review confirmed the need for a reporting checklist for consensus methodology and provided a range of potential checklist items to report. The next step in the ACCORD project builds on this systematic review and focuses on reaching consensus on these items to develop the reporting guideline.Protocol registrationhttps://osf.io/2rzm9.

Resumen

Abstract The Systematic Approach Forecast Aid (SAFA) has been in use at the Joint Typhoon Warning Center since the 2000 western North Pacific season. SAFA is a system designed for determination of erroneous 72-h track forecasts through identification of predefined error mechanisms associated with numerical weather prediction models. A metric for the process is a selective consensus in which model guidance suspected to have 72-h error greater than 300 n mi (1 n mi = 1.85 km) is first eliminated prior to calculating the average of the remaining model tracks. The resultant selective consensus should then provide improved forecasts over the nonselective consensus. In the 5 yr since its introduction into JTWC operations, forecasters have been unable to produce a selective consensus that provides consistent improved guidance over the nonselective consensus. Also, the rate at which forecasters exercised the selective consensus option dropped from approximately 45% of all forecasts in 2000 to 3% in 2004.

Resumen

Abstract The objective consensus forecasting (OCF) system is an automated operational forecasting system that adapts to underlying numerical model upgrades within 30 days and generally outperforms direct model output (DMO) and model output statistics (MOS) forecasts. It employs routinely available DMO and MOS guidance combined after bias correction using a mean absolute error (MAE)-weighted average algorithm. OCF generates twice-daily forecasts of screen-level temperature maxima and minima, ground-level temperature minima, evaporation, sunshine hours, and rainfall and its probability for day 0 to day 6 for up to 600 Australian sites. Extensive real-time trials of temperature forecasts yielded MAEs at days 0–2 about 40% lower than those from its component MOS and DMO forecasts. MAEs were also lower at day 1 than matching official forecasts of maxima and minima by 8% and 10% and outperformed official forecasts at over 71% and 75% of sites, respectively. MAEs of weighted average consensus outperformed simple average forecasts by about 5%.

Resumen

This paper studies a cooperative encirclement interception guidance law against a maneuvering target that utilizes a leader–follower control scheme. The control design is decoupled into two parts. In the line-of-sight (LOS) direction, a fixed-time distributed disturbance observer is presented to estimate the maneuvering of the target. Based on the proposed disturbance observer, the guidance law is designed for the followers to guarantee that each follower’s total flight time achieves consensus with that of the leader. In the normal direction of the LOS, the control command is designed to realize the encirclement interception with a predefined-time consensus protocol. The convergence of the guidance algorithm is proven by the Lyapunov stability theory. Numerical simulations are provided to demonstrate the effectiveness and superiority of the proposed cooperative-guidance law.

Resumen

BackgroundMany people are dying from coronavirus disease 2019 (COVID-19), but consensus guidance on palliative care in COVID-19 is lacking. This new life-threatening disease has put healthcare systems under pressure, with the increased need of palliative care provided to many patients by clinicians who have limited prior experience in this field. Therefore, we aimed to make consensus recommendations for palliative care for patients with COVID-19 using the Convergence of Opinion on Recommendations and Evidence (CORE) process.MethodsWe invited 90 international experts to complete an online survey including stating their agreement, or not, with 14 potential recommendations. At least 70% agreement on directionality was needed to provide consensus recommendations. If consensus was not achieved on the first round, a second round was conducted.Results68 (75.6%) experts responded in the first round. Most participants were experts in palliative care, respiratory medicine or critical care medicine. In the first round, consensus was achieved on 13 recommendations based upon indirect evidence and clinical experience. In the second round, 58 (85.3%) out of 68 of the first-round experts responded, resulting in consensus for the 14th recommendation.ConclusionThis multi-national task force provides consensus recommendations for palliative care for patients with COVID-19 concerning: advance care planning; (pharmacological) palliative treatment of breathlessness; clinician–patient communication; remote clinician–family communication; palliative care involvement in patients with serious COVID-19; spiritual care; psychosocial care; and bereavement care. Future studies are needed to generate empirical evidence for these recommendations.

Resumen

This guidance refers to urogenital atrophy, a chronic and progressive condition due to estrogen deficiency, most commonly associated with the menopause. There is a potential negative impact on all urogenital tissue quality including the vulva, vagina, bladder and urethra. Symptoms may not become apparent for several years after the menopause and therefore any association is lost, with women accepting symptoms as a normal part of the aging process. There may be reluctance to discuss symptoms with a clinician and this is likely to be linked with under diagnosis and under treatment. Urogenital atrophy has been described as a silent epidemic with lack of awareness affecting an accurate diagnosis and access to treatment. Whilst vaginal estrogen (also referred to as local estrogen) therapy is the best-known treatment, newer drugs and interventions are now available.

Resumen

This paper is concerning the simultaneous attack problem with multiple missiles against a maneuvering target with unknown acceleration. The new guidance protocol, which avoids using the time-to-go information, ensures the simultaneous attack based on the consensus of the range-to-go and the approaching rate of each missile. This strategy is a distributed guidance law where each missile can only get information from neighbors. The consensus of the missiles is shown mathematically as well as with extensive simulations.

Resumen

The target-encirclement guidance problem for many-to-one missile-target engagement scenario is studied, where the missiles evenly distribute on a target-centered circle during the homing guidance. The proposed distributed target-encirclement guidance law can achieve simultaneous attack of multiple missiles in different line-of-sight directions. Firstly, the decentralization protocols of desired line-of-sight angles are constructed based on the information of neighboring missiles. Secondly, a biased proportional navigation guidance law that can arbitrarily designate the impact angle is cited. The missiles can achieve all-aspect attack on the target in an encirclement manner by combining the biased proportional navigation guidance law and dynamic virtual targets strategy. Thirdly, the consensus protocol of simultaneous attack is designed, which can guarantee that all missiles’ time-to-go estimates achieve consensus asymptotically, and the convergence of the closed-loop system is proved strictly via the Lyapunov stability theory. Finally, numerical simulation results demonstrate the performance and feasibility of the proposed distributed target-encirclement guidance law in different engagement situations.

Resumen

ABSTRACTThis study focuses on the co-operative salvo attack problem of multiple missiles against a stationary target under jointly connected switching topologies subject to time-varying communication delays. By carefully exploring certain features of the typical pure proportional navigation guidance law, a two-stage distributed guidance scheme is proposed without any information on time-to-go in this study to realise the simultaneous attack of multiple missiles. In the first guidance stage, a co-operative guidance law is proposed using local neighbouring communications only to achieve consensus on range-to-go and heading error to provide favourable initial conditions for the latter phase, in which switching topologies and time-varying communication delays are taken into account when obtaining sufficient conditions of consensus in terms of linear matrix inequalities. Then, missiles disconnect from each other and are guided individually by the typical pure proportional navigation guidance law with the same navigation gain to realise salvo attack in the second guidance phase. Finally, numerical simulations are carried out to clearly validate the theoretical results.

Resumen

Central banks’ announcements that rates are expected to remain low could signal either a weak macroeconomic outlook, which would slow expenditures, or a more accommodative stance, which may stimulate economic activity. We use the Survey of Professional Forecasters to show that, when the Fed gave guidance between 2011:III and 2012:IV, these two interpretations coexisted despite a consensus on low expected rates. We rationalize these facts in a New-Keynesian model where heterogeneous beliefs introduce a trade-off in forward guidance policy: leveraging on the optimism of those who believe in monetary easing comes at the cost of inducing excess pessimism in non-believers.

Resumen

e24042 Background: Exercise has been shown to improve physical function and quality of life in individuals with bone metastases. To facilitate better integration of exercise services into clinical care for these more complex patients, the purpose was to understand the current views of an expert panel on the appropriate exercise screening approach for adults with bone metastases. Methods: Physicians, physical therapists and exercise physiologists with clinical or research expertise in providing medical and/or exercise advice to individuals with bone metastases were identified. A 3-round modified online Delphi survey was used to establish a consensus, with a priori consensus set to 70%. Results: Response rates were 68% (73/107), 81% (59/73) and 97% (57/59) for each Delphi round. Key consensus points were: a) medical guidance (i.e. communication and medical information from a physician) is recommended prior to commencing structured exercise for all individuals with bone lesions (90% consensus) and is required when individuals present with bone pain, have received past medical treatment for bone pain, or have a history of disease-related fractures (90% consensus); b) the primary objective of exercise professionals for seeking medical guidance is to obtain medical information (e.g., bone scan reports) to guide clinical decision making for exercise prescription (93% consensus) and for bi-directional communication (i.e., for overall patient care and safety) (75% consensus) versus requiring a direct referral from a physician for liability coverage (39% consensus); c) the physician group that exercise professionals most commonly approach for medical guidance are medical oncologists (84% consensus) or radiation oncologists (63% consensus) compared to primary care providers (33% consensus), orthopedic surgeons (40% consensus) or physiatrists (16%); d) as part of pre-exercise screening by an exercise professional, information should be collected on the number, location and type of bone lesion(s), level of bone pain and any other bone-related symptom (100% consensus). Conclusions: This represents the current views of a range of physicians, physical therapists, exercise physiologists and researchers who provide medical and/or exercise advice to adults with bone metastases. These findings will inform the work of the International Bone Metastases Exercise Working Group to establish the first exercise guidelines for adults with bone metatases.

Resumen

Abstract New multi-lead-time versions of three statistical probabilistic tropical cyclone rapid intensification (RI) prediction models are developed for the Atlantic and eastern North Pacific basins. These are the linear-discriminant analysis–based Statistical Hurricane Intensity Prediction Scheme Rapid Intensification Index (SHIPS-RII), logistic regression, and Bayesian statistical RI models. Consensus RI models derived by averaging the three individual RI model probability forecasts are also generated. A verification of the cross-validated forecasts of the above RI models conducted for the 12-, 24-, 36-, and 48-h lead times indicates that these models generally exhibit skill relative to climatological forecasts, with the eastern Pacific models providing somewhat more skill than the Atlantic ones and the consensus versions providing more skill than the individual models. A verification of the deterministic RI model forecasts indicates that the operational intensity guidance exhibits some limited RI predictive skill, with the National Hurricane Center (NHC) official forecasts possessing the most skill within the first 24 h and the numerical models providing somewhat more skill at longer lead times. The Hurricane Weather Research and Forecasting Model (HWRF) generally provides the most skillful RI forecasts of any of the conventional intensity models while the new consensus RI model shows potential for providing increased skill over the existing operational intensity guidance. Finally, newly developed versions of the deterministic rapid intensification aid guidance that employ the new probabilistic consensus RI model forecasts along with the existing operational intensity model consensus produce lower mean errors and biases than the intensity consensus model alone.

Resumen

In this paper, a cooperative guidance law based on consensus theory is proposed for multiple flight vehicles against a maneuvering target in a three-dimensional plane. The proposed guidance law has three orientation components: the one along the line-of-sight (LOS) ensures that all flight vehicles reach the target simultaneously, and the other two normal to the LOS in longitudinal and lateral plane guarantee the accurate interception. The target maneuverings are estimated by a finite-time convergence disturbance observer (FTDOB) and are compensated into the kinematic equation to achieve more accurate interception. Using the Lyapunov stability theorem, time-to-go of all flight vehicles’ convergence is proved. Mathematical simulations verify the effectiveness of the proposed cooperative guidance law.

Resumen

The aim was to capture interdisciplinary expertise from a large group of clinicians, reflecting practice from across the UK and further, to inform subsequent development of a national consensus guidance for optimal management of idiopathic intracranial hypertension (IIH).MethodsBetween September 2015 and October 2017, a specialist interest group including neurology, neurosurgery, neuroradiology, ophthalmology, nursing, primary care doctors and patient representatives met. An initial UK survey of attitudes and practice in IIH was sent to a wide group of physicians and surgeons who investigate and manage IIH regularly. A comprehensive systematic literature review was performed to assemble the foundations of the statements. An international panel along with four national professional bodies, namely the Association of British Neurologists, British Association for the Study of Headache, the Society of British Neurological Surgeons and the Royal College of Ophthalmologists critically reviewed the statements.ResultsOver 20 questions were constructed: one based on the diagnostic principles for optimal investigation of papilloedema and 21 for the management of IIH. Three main principles were identified: (1) to treat the underlying disease; (2) to protect the vision; and (3) to minimise the headache morbidity. Statements presented provide insight to uncertainties in IIH where research opportunities exist.ConclusionsIn collaboration with many different specialists, professions and patient representatives, we have developed guidance statements for the investigation and management of adult IIH.

Resumen

Abstract Because the Joint Typhoon Warning Center (JTWC) has only four dynamical models for guidance in making 96- and 120-h track forecasts, an opportunity exists for improving the consensus forecast by the proper removal of a likely erroneous forecast to form a selective consensus (SCON). Forecast fields from all four models [the U.S. Navy Operational Global Atmospheric Prediction System (NOGAPS), the U.S. Navy version of the Geophysical Fluid Dynamics Laboratory model (GFDN), the Met Office (UKMO) model, and the Global Forecast System (GFS)] were available during the 2005 western North Pacific season to evaluate for the first time the error mechanisms leading to large track errors. As shown previously for the NOGAPS and GFDN models during the 2004 season, error sources related to the midlatitude circulations accounted for about 90% of all large 120-h track errors by all four models during the 2005 season. This dominance of midlatitude-related error source is a major shift from the 72-h errors, which include more errors related to tropical circulations. In the GFS model, 95% of the large errors occurred because of an incorrect depiction of the vertical structure of the tropical cyclone. A systematic error in the GFDN model was identified in which a false anticyclogenesis was predicted downstream of the Tibetan Plateau, which accounted for over 50% of the large GFDN track errors. The consensus spread versus consensus error relationship is examined to isolate those 20%–25% of cases with large spreads and large errors that are candidates for forming an SCON. If the model tracks that contributed to the large errors are eliminated, the average improvement of the SCON forecasts relative to the nonselective consensus is 222 (239) n mi during 2005 (2004), and the corresponding average improvement relative to the JTWC forecasts is 382 (203) n mi. This application of SCON is considered the potential “forecastability” in that it represents the optimum use of the present numerical guidance for consensus forecasting.

Resumen

In the last decade, long-acting injectable antipsychotics has been widely used in schizophrenia. Aripiprazole long-acting once-monthly (AOM) is the only long-acting dopamine partial agonist antipsychotic approved for schizophrenia; however, a literature search revealed no guidance on safely switching from oral and long-acting injectable antipsychotics to AOM. This study aimed to develop recommendations of AOM use based on existing data and expert consensus. A committee of 30 experts in psychopharmacology from major hospitals across Taiwan was invited. A modified Delphi method was conducted, consisting of two rounds of questionnaires, literature review, three rounds of face-to-face discussion meeting, and two rounds of anonymous voting. The consensus recommendations were developed based on existing data, clinical experiences, and consensus opinions, with 80% agreement among panel members required for final adoption. The panel developed nine consensus statements of switching to AOM for both acute and stable schizophrenia patients receiving oral or long-acting injectable atypical antipsychotics. Recommendations regarding dose adjustment of oral medication and pregnancy/breastfeeding were also included. The nine consensus recommendations provide a guidance on safely switching to AOM. Substantial gaps in knowledge, and more research is necessary.

Resumen

Abstract Purpose: The vacuum biopsy of the breast under sonographic guidance (VB) was introduced in Germany in the year 2000 and the first consensus recommendations were published by Krainick-Strobel et al. in 2005. Since then, many clinical studies on this technique have been published. The purpose of this publication is to update the consensus recommendations from 2005 regarding the latest literature. Materials and Methods: The consensus statements were the result of two preliminary meetings after the review of the latest literature by members of the Minimally Invasive Breast Intervention Study Group from the German Society of Senology. The final consensus text was review by all members of the working group. The statements listed under results obtained complete acceptance (consensus 100 %). Results: The consensus recommendations describe the indications, investigator qualifications, technical requirements, documentation, quality assurance and follow-up intervals regarding the latest literature. Conclusion: The VB is a safe method for extracting breast tissue for histological workup. The technique allows the resection of breast tissue up to 8 cm3. Besides the diagnostic indications, the method qualifies for a therapeutic resection of symptomatic benign lesions (e. g. fibroadenomas). The technique should be used in specialized breast centers working in a multidisciplinary setup. This paper is an expert’s recommendation for the use of VB under sonographic guidance. It is not formulated as a nationwide guideline.
