Abstract
Cystic fibrosis (CF) is a multisystem, genetic disease with a significantly reduced life expectancy. Despite substantial progress in therapies in the last 10-15 years, there is still no cure. There are dozens of drugs in the development pipeline and multiple clinical trials are being conducted across the globe. The UK Cystic Fibrosis Trust's (CFT) Clinical Trials Accelerator Platform (CTAP) is a national initiative bringing together 25 UK based CF centres to support the CF community in accessing and participating in CF clinical trials. CTAP enables more CF centres to run a broader portfolio of trials and increases the range of CF studies available for UK patients. There are four large specialist CF centres based in London, all within a small geographical region as well as two smaller centres which deliver CF care. At the launch of CTAP, these centres formed a sub-network in a consortium-style collaboration. The purpose of the network was to ensure equity of access to trials for patients across the UK's capital, and to share experience and knowledge. Four years into the programme we have reviewed our practices through working group meetings and an online survey. We sought to identify strengths and areas for improvement. We share our findings here, as we believe they are relevant to others delivering research in regions outside of London and in other chronic diseases.

Abstract
BACKGROUND Antibiotic eradication therapies recommended for newly isolated Pseudomonas aeruginosa (Pa) in people with cystic fibrosis (pwCF) can be burdensome. ALPINE2 compared the efficacy and safety of a shortened 14-day course of aztreonam for inhalation solution (AZLI) with 28-day AZLI in paediatric pwCF. METHODS ALPINE2 (a double-blind, phase 3b study) included children aged 3 months to <18 years with CF and new-onset Pa infection. Participants were randomized to receive 75 mg AZLI three times daily for either 28 or 14 days followed by 14 days' matched placebo. The primary endpoint was rate of primary Pa eradication (no Pa detected during the 4 weeks post AZLI treatment). Non-inferiority was achieved if the lower 95% CI bound of the treatment difference between the two arms was above -20%. Secondary endpoints included assessments of Pa recurrence during 108 weeks of follow-up after primary eradication. Safety endpoints included treatment-emergent adverse events (TEAEs). RESULTS In total, 149 participants were randomized (14-day AZLI, n = 74; 28-day AZLI, n = 75) and 142 (95.3%) completed treatment. Median age: 6.0 years (range: 0.3-17.0). Baseline characteristics were similar between treatment arms. Primary Pa eradication rates: 14-day AZLI, 55.9%; 28-day AZLI, 63.4%; treatment difference (CI), -8.0% (-24.6, 8.6%). Pa recurrence rates at follow-up end: 14-day AZLI, 54.1% (n = 20/37); 28-day AZLI, 41.9% (n = 18/43). TEAEs were similar between treatment arms. No new safety signals were observed. CONCLUSIONS Non-inferiority of 14-day AZLI versus 28-day AZLI was not demonstrated. Both courses were well tolerated, further supporting AZLI short-term safety in paediatric and adolescent pwCF.

Abstract
Post-acute COVID-19 causes long term sequalae in adults. This is less well described in children. We performed clinical assessments on a large cohort of children and young people admitted with a positive SARS-CoV-2 RNA swab. We assessed for symptoms of post-acute COVID-19 syndrome after 4 weeks or more. We found that most (85%) of children made a full recovery following SARS-CoV-2 infection. A small number had symptoms which lasted for more than 4 weeks, most of which had resolved at 3 months. Symptoms included dry cough, fatigue and headache. One patient suffered from anosmia. We conclude that most children and young people do not suffer from past-acute COVID-19 syndrome, and make a full recovery from infection.

Abstract
AbstractThe term citizen science refers to a broad set of practices developed in a growing number of areas of knowledge and characterized by the active citizen participation in some or several stages of the research process. Definitions, classifications and terminology remain open, reflecting that citizen science is an evolving phenomenon, a spectrum of practices whose classification may be useful but never unique or definitive. The aim of this article is to study citizen science publications in journals indexed by WoS, in particular how they have evolved in the last 20 years and the collaboration networks which have been created among the researchers in that time. In principle, the evolution can be analyzed, in a quantitative way, by the usual tools, such as the number of publications, authors, and impact factor of the papers, as well as the set of different research areas including citizen science as an object of study. But as citizen science is a transversal concept which appears in almost all scientific disciplines, this study becomes a multifaceted problem which is only partially modelled with the usual bibliometric magnitudes. It is necessary to consider new tools to parametrize a set of complementary properties. Thus, we address the study of the citizen science expansion and evolution in terms of the properties of the graphs which encode relations between scientists by studying co-authorship and the consequent networks of collaboration. This approach - not used until now in research on citizen science, as far as we know- allows us to analyze the properties of these networks through graph theory, and complement the existing quantitative research. The results obtained lead mainly to: (a) a better understanding of the current state of citizen science in the international academic system-by countries, by areas of knowledge, by interdisciplinary communities-as an increasingly legitimate expanding methodology, and (b) a greater knowledge of collaborative networks and their evolution, within and between research communities, which allows a certain margin of predictability as well as the definition of better cooperation strategies.

Abstract
INTRODUCTION Treatment of peripheral facial palsy with botulinum toxin A is safe and effective. Although its beneficial impact on patients' quality of life is known, to date, there have been no studies specifically analysing patients' subjective perceptions. PATIENTS AND METHOD We performed a prospective study in a random sample of patients with sequels of peripheral facial palsy treated with botulinum toxin in the Physical Medicine and Rehabilitation Service of our hospital. We created a simple questionnaire to assess both patient satisfaction and subjective perception of improvement after botulinum toxin treatment. RESULTS After infiltration, 95% of the patients felt good or very good. More than 80% noted improvement in the sensation of tightness in the cheek and neck. Around 75% of patients perceived an improvement in the range of voluntary movement and approximately 80% reported improvement in synkinesis. Almost all the patients would repeat the treatment, if proposed, and 100% would recommend botulinum toxin infiltration to other patients with facial palsy. CONCLUSIONS Patients treated with botulinum toxin experience substantial subjective improvement in the sequels of peripheral facial palsy, both in repose and in the control of synkinesis. Satisfaction was higher than 8/10 in 99% of patients in this study.

Abstract
INTRODUCTION Sickle cell disease (SCD) is one of the most common inherited diseases worldwide. It is associated with lifelong morbidity and reduced life expectancy. Hydroxyurea (HU) has been shown to reduce the frequency and severity of vaso-occlusive episodes in SCD. Hypoxaemia and intermittent nocturnal oxygen desaturations occur frequently in children with SCD and contribute to the associated morbidity, including risk of cerebrovascular disease. OBJECTIVE To evaluate the effect of HU on oxygen saturation (SpO2) overnight and on daytime SpO2 spot checks in children with SCD. METHODS A retrospective review of children with SCD and respiratory problems who attended two UK tertiary sickle respiratory clinics and were treated with HU. Longitudinal data were collected from 2 years prior and up to 3 years after the commencement of HU. RESULTS Forty-three children, 23 males (53%) with a median age of 9 (range 1.8-18) years were included. In the 21 children who had comparable sleep studies before and after starting HU, mean SpO2 was higher (95.2% from 93.5%, p=0.01) and nadir SpO2 was higher (87.2% from 84.3%, p=0.009) when taking HU. In 32 of the children, spot daytime oxygen saturations were also higher (96.3% from 93.5%, p=0.001). CONCLUSION Children with SCD had higher oxygen saturation overnight and on daytime spot checks after starting HU. These data suggest HU may be helpful for treating persistent hypoxaemia in children with SCD pending more evidence from a randomised clinical trial.

Abstract
BACKGROUND With the widespread introduction of newborn screening for cystic fibrosis (CF), there has been considerable emphasis on the need to develop objective markers of lung health that can be used during infancy. We hypothesised that in a newborn screened (NBS) UK cohort, evidence of airway inflammation and infection at one year would be associated with adverse structural and functional outcomes at the same age. METHODS Infants underwent lung function testing, chest CT scan and bronchoscopy with bronchoalveolar lavage (BAL) at 1 year of age when clinically well. Microbiology cultures were also available from routine cough swabs. RESULTS 65 infants had lung function, CT and BAL. Mean (SD) lung clearance index and forced expiratory volume in 0.5 s z-scores were 0.9(1.2) and -0.6(1.1) respectively; median Brody II CF-CT air trapping score on chest CT =0 (interquartile range 0-1, maximum possible score 27). Infants isolating any significant pathogen by 1 yr of age had higher LCI z-score (mean difference 0.9; 95%CI:0.4-1.4; p = 0.001) and a trend towards higher air trapping scores on CT (p = 0.06). BAL neutrophil elastase was detectable in 23% (10/43) infants in whom BAL supernatant was available. This did not relate to air trapping score on CT. CONCLUSIONS In this UK NBS cohort at one year of age, lung and airway damage is much milder and associations between inflammation, abnormal physiology and structural changes were at best weak, contrary to our hypothesis and previously published reports. Continued follow-up will clarify longer term implications of these very mild structural, functional and inflammatory changes.

Abstract
OBJECTIVES To investigate the agreement between pulse oximetry (SpO2) and oxygen saturation (SaO2) measured by CO-oximetry on arterialised earlobe blood gas (EBG) in children and adolescents with sickle cell disease (SCD). DESIGN AND SETTING We retrospectively reviewed 39 simultaneous and paired SaO2 EBG and SpO2 measurements from 33 ambulatory patients with SCD (32 subjects with Haemoglobin SS and one with Haemoglobin Sß+, 52% male, mean±SD age 11.0±3.6, age range 5-18). Measurements were performed between 2012 and 2015 when participants were asymptomatic. Hypoxaemia was defined as SaO2 ≤93%. A Bland-Altman analysis was performed to assess the accuracy of SpO2 as compared with EBG SaO2. RESULTS The mean±SD SpO2 and SaO2 values in the same patients were, respectively, 93.6%±3.7% and 94.3%±2.9%. The bias SpO2-SaO2 was -0.7% (95% limits of agreement from -5.4% to 4.1%) and precision was 2.5%. In 9/39 (23%) cases, the difference in SpO2-SaO2 was greater than the expected error range ±2%, with SaO2 more often underestimated by SpO2 (6/9), especially at SpO2values ≤93%. Thirteen participants (33%) were hypoxaemic. The sensitivity of SpO2 for hypoxaemia was 100%, specificity 85% and positive predictive value 76%. CONCLUSIONS Pulse oximetry was inaccurate in almost a quarter of measurements in ambulatory paediatric patients with SCD, especially at SpO2values ≤93%. In these cases, oxygen saturation can be confirmed through EBG CO-oximetry, which is easier to perform and less painful than traditional arterial blood sampling.

Abstract
Background We hypothesized that the abundance of PD1 mRNA in tumor samples might explain the differences in overall response rates (ORR) observed following anti-PD1 monotherapy across cancer types. Patients and methods RNASeqv2 data from 10 078 tumor samples representing 34 different cancer types was analyzed from TCGA. Eighteen immune-related gene signatures and 547 immune-related genes, including PD1, were explored. Correlations between each gene/signature and ORRs reported in the literature following anti-PD1 monotherapy were calculated. To translate the in silico findings to the clinical setting, we analyzed the expression of PD1 mRNA using the nCounter platform in 773 formalin-fixed paraffin embedded (FFPE) tumor samples across 17 cancer types. To test the direct relationship between PD1 mRNA, PDL1 immunohistochemistry (IHC), stromal tumor-infiltrating lymphocytes (sTILs) and ORR, we evaluated an independent FFPE-based dataset of 117 patients with advanced disease treated with anti-PD1 monotherapy. Results In pan-cancer TCGA, PD1 mRNA expression was found strongly correlated (r > 0.80) with CD8 T-cell genes and signatures and the proportion of PD1 mRNA-high tumors (80th percentile) within a given cancer type was variable (0%-84%). Strikingly, the PD1-high proportions across cancer types were found strongly correlated (r = 0.91) with the ORR following anti-PD1 monotherapy reported in the literature. Lower correlations were found with other immune-related genes/signatures, including PDL1. Using the same population-based cutoff (80th percentile), similar proportions of PD1-high disease in a given cancer type were identified in our in-house 773 tumor dataset as compared with TCGA. Finally, the pre-established PD1 mRNA FFPE-based cutoff was found significantly associated with anti-PD1 response in 117 patients with advanced disease (PD1-high 51.5%, PD1-intermediate 26.6% and PD1-low 15.0%; odds ratio between PD1-high and PD1-intermediate/low = 8.31; P < 0.001). In this same dataset, PDL1 tumor expression by IHC or percentage of sTILs was not found associated with response. Conclusions Our study provides a clinically applicable assay that links PD1 mRNA abundance, activated CD8 T-cells and anti-PD1 efficacy.

Abstract
Las Tecnologías del Aprendizaje y el Conocimiento (TAC) tienen una influencia cada vez mayor en la manera de mediar el aprendizaje de los más jóvenes. El incremento del proceso de enseñanza y aprendizaje mediado por las TAC en el ámbito de la educación y en el ámbito doméstico, induce a la creación de nuevas herramientas efectivas, avaladas por la ciencia y diseñadas para mejorar el aprendizaje de nuestros alumnos. El desafío al que se enfrenta la psicología de la educación consiste en fomentar éstas tecnologías y ponerlas al servicio de la comunidad educativa y sin perder de vista el hecho de generar productos atractivos para los usuarios y que puedan generar rendimiento comercial para las empresas. Pretendiendo generar además de una transferencia efectiva de la labor científica, el aumento en la visibilidad de la investigación. En este trabajo, presentamos 9 aplicaciones (APPs) diseñadas para Tablet y Smartphone, adaptadas a los diferentes sistemas operativos actuales, destinadas a trabajar sobre las bases cognitivas asociadas con el aprendizaje de la matemática temprana. Con el objeto de crear una herramienta atractiva para el alumnado de 4 a 7 años, se ha contado con la colaboración de la empresa de entretenimiento y divulgación infantil Babyradio, colaborando en el desarrollo gráfico y en la transferencia de los resultados de la inves tigación. Una vez demostrada la validez empírica de estas APPs, los maestros, el sistema educativo y las empresas de software dispondrían de un material de apoyo didáctico contrastado. El objetivo principal del trabajo es contribuir en el desarrollo de las habilidades matemáticas de los niños de 4 a 7 años para que estos puedan afrontar con éxito los requerimientos de la escuela y para que puedan resolver situaciones en sus vidas diarias, promoviendo por otro lado, el cambio actitudinal del alumnado con respecto a las matemáticas

Abstract
Newborn babies positively screened for cystic fibrosis (CF) (high serum immunoreactive trypsin (IRT) with DNA analysis) are referred for a diagnostic sweat test, which may be normal (sweat chloride <30 mmol/L). Unless two gene mutations are identified during Newborn screening (NBS), the babies are discharged from follow-up. We wished to check that none had subsequently developed symptoms suggestive of CF. We retrospectively reviewed patient notes and contacted general practitioners of all babies with a negative sweat test, conducted in one of the four paediatric specialist CF centres in London, over the first 6 years of screening in South East England.Of 511 babies referred, 95 (19%) had a normal sweat test. Five (5%) had CF diagnosed genetically, two of them on extended genome sequencing after clinical suspicion. Eleven (12%) were designated as CF screen positive inconclusive diagnosis (CFSPID); one of the five CF children was originally designated as CFSPID. Seventy-nine (83%) were assumed to be false-positive cases and discharged; follow-up data were available for 51/79 (65%); 32/51 (63%) had no health issues, 19/51 (37%) had other significant non-CF pathology.These results are reassuring in that within the limitations of those lost to follow-up, CF symptoms have not emerged in the discharged children. The high non-CF morbidity in these children may relate to known causes of high IRT at birth. Clinicians need to be aware that a child can have CF despite a normal sweat test following NBS, and if symptoms suggest the diagnosis, further testing, including extended genome sequencing, is required.

Abstract
PURPOSE This study was performed to determine whether components of the standard ERG (electroretinogram), multifocal ERG, and flash VECP (visually-evoked cortical potential) response might provide a sensitive measure of retinal ganglion cell injury in a monkey model for chronic ocular hypertension. METHODS Argon laser treatment of the aqueous outflow tissue was used to induce chronic elevation of intraocular pressure (IOP) in the right eye of 18 young adult cynomolgous monkeys. At 15 months post- IOP elevation, standard methods were used to record ERG and VECP responses. Multifocal ERG responses were also recorded at this time. Loss of retinal ganglion cells due to ocular hypertensive injury was determined by histological analysis of all retinas. RESULTS Ocular hypertensive retinal injury was associated with a loss of retinal ganglion cells. There was no histological or electrophysiological evidence for injury to any other retinal cell type. Correlation of electrophysiological response amplitudes with histological measures of retinal ganglion cell loss/survival yielded results which suggest that activity in retinal ganglion cells makes a substantial contribution to components of the 30 Hz flicker ERG, the flash VECP, and both first and second order multifocal ERG responses. Of the electrophysiological measures used in this study, multifocal ERG response amplitude had the greatest sensitivity to retinal ganglion cell loss. CONCLUSIONS Components of the multifocal ERG provide a sensitive measure of ganglion cell injury in a monkey model of chronic ocular hypertension. These same measures may have utility in the clinical diagnosis and management of glaucoma.

Abstract
SummaryCoagulation studies were performed in 52 patients with sickle cell disease during asymptomatic periods and during episodes of crisis and infection. Platelet counts averaged 473,000, 469,000, and 461,000 per mm3 in these 3 groups, and factor VIII concentrations were elevated in all. Fibrinogen was increased to the same extent in both sickle cell and non-sickle cell patients with infection. Fibrinolytic activity, as measured by euglobulin lysis times and zones of lysis on fibrin plates, was markedly reduced during periods of infection in sickle cell patients but not in non-sickle patients. Impairment of fibrinolysis in most patients was not on the basis of overutilization or consumption, since no decrease in the levels of clotting factors or plasminogen was observed. It was suggested that generalized intravascular sickling in these patients may have caused widespread endothelial damage, resulting in decreased production of plasminogen activator.In addition, several sickle cell patients with infection were found to possess elevated levels of an inhibitor directed against urokinase.

Abstract
Coughing is a primary pulmonary defence mechanism that enhances clearance of secretions and particles from the airways and protects against aspiration of foreign materials. Coughing may affect 30% of children at any given time (1). Many are healthy children but some may have serious underlying disease. Childhood cough accounts for a large number of consultations and 80% of families who are referred to a paediatric respiratory clinic for chronic cough have sought medical advice five times or more (2). The majority of childhood coughs are secondary to an acute respiratory tract infection and will improve once the infection resolves, usually within 1 to 3 weeks. With pre-school children who may experience between 6 and 10 respiratory infections a year differentiating acute recurrent cough from chronic cough is key (Table 1). Chronic cough can significantly impact a family's quality of life, as it affects the child's sleep, school attendance and play. Parents experience distress and anxiety, worrying that the cough may lead to long-term chest damage or even death (3). This article aims to guide clinicians through the assessment of the child with a chronic cough. It will discuss identifying causes, use of first line investigations, initiating appropriate management and addressing parental anxiety and exacerbating factors (4,5).

Abstract
BACKGROUND We have found clusters of Klebsiella pneumoniae with OXA48-carbepenemase cases in some hospital rooms, and decided to investigate whether bathroom siphons could be a reservoir for OXA48 bacteria, as occurs with K. oxytoca with other types of carbepenemases. METHODS We evaluated the microbial competition between strains with OXA48 and VIM carbepenemases, in diluted nutrient-broth, on a slime germ-carrier. We compared the number of colonies at 5 and 10 days on the contaminated carriers with one or two strains. We evaluated the dissemination of K. pneumoniae with carbepenemase OXA48 or VIM from thumbs and index fingers of volunteers, to standard surfaces (20 glass germ-carrier by each volunteer). After, we counted the number of microorganisms on each carrier. Microbiological weekly studies of faecal microbiota of all patients were obtained in Traumatology and Oncology. Moreover, we studied samples of the sink in their rooms. PCR and MLST sequence-type was determined in all K. pneumoniae diagnosed from patients and sinks. RESULTS A large possibility of diffusion from contaminated hands, which continue to transmit high numbers of microorganisms after more than 10 successive surface contacts, was highlighted; OXA bacteria were more persistent than VIM bacteria. Microbial competition studies showed that VIM bacteria are inhibited by OXA ones. These observations can explain the concentration of cases of K. pneumoniae OXA48 in some rooms in Traumatology and Oncology, producing a significant OR between rooms with OXA48-bacteria-contaminated siphons and other rooms (3.1 and 3.3 respectively). Risk was lowered after changing or disinfecting (heat plus chlorinated disinfectant) the contaminated siphons. Siphon colonization by VIM bacteria was not related with human infections by similar microorganisms. CONCLUSIONS Bathroom siphons can be a reservoir for K. pneumoniae OXA48 and lead to outbreaks. Outbreaks can be controlled by replacement or heat plus chemical treatment of the sink-siphons.

Abstract
UNLABELLED There is conflicting evidence of the effectiveness of montelukast in preschool wheeze. A recent Cochrane review focused on its use in viral-induced wheeze; however, such subgroups are unlikely to exist in real life and change with time, recently highlighted in an international consensus report. We have therefore sought to investigate the effectiveness of montelukast in all children with preschool wheeze (viral-induced and multiple-trigger wheeze). The PubMed, Cochrane Library, Ovid Medline and Ovid EMBASE were screened for randomised controlled trials (RCTs), examining the efficacy of montelukast compared with placebo in children with the recurrent preschool wheeze. The primary endpoint examined was frequency of wheezing episodes. Five trials containing 3960 patients with a preschool wheezing disorder were analysed. Meta-analyses of studies of intermittent montelukast showed no benefit in preventing episodes of wheeze (mean difference (MD) 0.07, 95% confidence interval (CI) -0.14 to 0.29; mean for montelukast 2.68 vs placebo 2.54 (p = 0.5)), reducing unscheduled medical attendances (MD -0.13, 95% CI -0.33 to 0.07; mean for montelukast 1.62 vs placebo 1.78 (p = 0.21)) and reducing oral corticosteroids (MD -0.06, 95% CI -0.16 to 0.02; mean for montelukast 0.35 vs placebo 0.36 (p = 0.25)). The pooled results of the continuous regimen showed no significant difference in the number of wheezing episodes between the montelukast and placebo groups (MD -0.40, 95% CI -1.00 to 0.19; mean for montelukast 2.05 vs placebo 2.37 (p = 0.18)). CONCLUSIONS This review highlights that the currently available evidence does not support the use of montelukast in preschool children with recurrent wheeze. We recommend further studies to investigate if a 'montelukast responder' phenotype exists, and how these can be easily identified in the clinical setting. What is Known: • Current guidelines recommend montelukast use in preschool children with recurrent wheeze. • A recent Cochrane review has found montelukast to be ineffective at reducing courses of oral corticosteroids for viral-induced wheeze. What is New: • This meta-analysis has examined all children with preschool wheeze and found that montelukast was not effective at preventing wheezing episodes or reducing unscheduled medical attendances. • A specific montelukast responder phenotype may exist, but such patients should be sought in larger multicentre RCTs.

Abstract
OBJECTIVES The aims of this study were to compare cytological samples obtained from endoscopic biopsies using "imprint" and "squash" techniques, and to evaluate the potential value of cytology compared to histology in reaching the diagnosis. MATERIALS AND METHODS Eighteen dogs and five cats undergoing endoscopy for chronic gastrointestinal signs were prospectively included. Imprint and squash samples were obtained from one biopsy and then analysed. Comparison between cytology and histology was performed using Cohen's j coefficient. RESULTS Appropriate samples for cytological evaluation were more often obtained with the squash technique (96% of the cases versus 68% with the imprint technique). The diagnoses obtained with cytological samples and by histology, considered as the gold standard, were compared. The same diagnosis was obtained with the squash technique in 65% of the cases. Furthermore, cytology was considered complementary to histology for gastric spiral organisms and mast cells identification. CLINICAL SIGNIFICANCE These results suggest that squash cytology obtained from endoscopic biopsies of the gastrointestinal tract can provide relevant and additional information to histology in dogs and cats.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Dandelion (Taraxacum spec) is a wild plant that has been used for centuries as a traditional medicine in the relief and treatment of several diseases. This use is due to the presence of sesquiterpenes, saponins, phenolic compounds, flavonoids, and sugars, among others, found in the organs of the plant. AIM OF THE STUDY The aim of this work is to provide a current review of developments and trends in research on the Taraxacum genus, with a focus on traditional uses and pharmacological properties. This should shed light on the potential of this plant as an attractive commercial herbal medicine. MATERIALS AND METHODS Documents were collected, analyzed, and classified for information regarding medical, agronomic, genetic, and biological aspects of the Taraxacum species. This process was based on a thorough search of documents indexed by scientific search engines. RESULTS Two important periods of research on Taraxacum have been identified: the first, between 1930 and 1950; and the second, from 1990 to today. During the former, agricultural and genetics research on this plant were, due to the shortage of natural rubber, the focus. In contrast, the main drive in Taraxacum research is now the recovery of bioactives and/or applications in medicine. Pharmacology is the main area in which these plants have been tested, thanks in part to its widely known traditional uses; however, there is less than enthusiastic interest in further human clinical trials. In other areas, Taraxacum sports an enormous list of compounds of industrial interest; and while it is true that only a small amount of these compounds is immediately available in Taraxacum organs and makes it relatively commercially unattractive, only scarce efforts have been made to improve yields. Compounding this issue, most studies of its growth and cultivation have been focused mainly on controlling it as a weed detrimental to certain industrial crops. To wit, in spite of all the research carried out, less than 1% of all the species identified so far (>2500) have been studied (including Taraxacum officinale, Taraxacum coreanum, Taraxacum mongolicum and Taraxacum platycarpum). This is a indication of the little knowledge that we have about this genus so far. Biotechnology (involving genetics, agriculture, and biology) is the most powerful means by which to take advantage of all the medicinal potential of Taraxacum. Great strides have been made in identifying metabolic pathways for synthesizing terpenes, one of the most important compound families in clinical applications. In order to improve yield and performance of the plant in the field, greenhouse cultivation is another aspect taken into account, deriving an increase in recovery of bioactives from Taraxacum organs. Even while considering that only a few species have been studied, their different biochemical and cultivation profiles indicate huge potential for qualitative improvements in composition through genetic engineering, thus directly impacting pharmacological properties. CONCLUSIONS Taraxacum is has been traditionally considered a natural remedy, well-inserted into popular knowledge, but with low commercial applicability. Only once the recovery of pure and highly reactive compounds can be pursued at (a qualitatively and quantitatively attractive) economical scale, human clinical trials would be of interest in order to prove their efficacy and safety, positioning Taraxacum as an important commercial source of natural drugs.
