RESUMEN
Androgenetic alopecia (AGA) is the most prevalent type of hair loss. Its morbility is mainly psychological although an increased incidence in melanoma has also been observed in affected subjects. Current drug based therapies and physical treatments are either unsuccessful in the long term or have relevant side effects that limit their application. Therefore, a new therapeutic approach is needed to promote regenerative enhancement alternatives. These treatment options, focused on the cellular niche restoration, could be the solution to the impact of dihydrotestosterone in the hair follicle microenvironment. In this context emerging regenerative therapies such as Platelet-rich plasma or Platelet-rich fibrine as well as hair follicle stem cells and mesenchymal stem cell based therapies and their derivatives (conditioned medium CM or exoxomes) are highlighting in the evolving landscape of hair restoration. Nanotechnology is also leading the way in AGA treatment through the design of bioinks and nanobiomaterials whose structures are being configuring in a huge range of cases by means of 3D bioprinting. Due to the increasing number and the rapid creation of new advanced therapies alternatives in the AGA field, an extended review of the current state of art is needed. In addition this review provides a general insight in current and emerging AGA therapies which is intented to be a guidance for researchers highlighting the cutting edge treatments which are recently gaining ground.

AIMS: The main objective in this study was to determine the prevalence of Chronic Kidney Disease (CKD) in people with Type 2 Diabetes Mellitus (T2DM) in the Autonomous Community (AC) of Aragon (Spain) and to detect whether or not there is under-registration in the patient's history. As a secundary objetive, it was proposed to study the most relevant demographic and clinical characteristics of people with CKD. METHODS: Observational and retrospective real world data study of the population over 18 years of age with a diagnosis of T2DM, between January 2017 and December 2021. A descriptive analysis of qualitative and quantitative variables, and a comparison using the parametric Student's t-test or the non-parametric Mann-Whitney U-test between both groups was performed. RESULTS: The prevalence of T2DM was 8.07â¯% and that of CKD 31.4â¯%, with an under-reporting of 47â¯%. The main risk factor associated with CKD was arterial hypertension (p<0.001), followed by dyslipidemia (p<0.001). The main treatment used for diabetes control was metformin, both in patients with and without CKD (p<0.001). A total of 56.81â¯% of people with T2DM and CKD did not undergo annual monitoring of their renal function (glomerular filtration rate) or determination of albuminuria. CONCLUSIONS: The prevalence of CKD increases in patients with T2DM (31.4â¯%), and in almost half of patients the diagnosis is not registered (47â¯%). This under-reporting delays the implementation of measures needed to prevent CKD progression.
RESUMEN
BACKGROUND AND STUDY AIMS: Our aim was to determine the impact of the SARS-CoV-2 pandemic on the diagnosis and prognosis of colorectal cancer (CRC). PATIENTS AND METHODS: This prospective cohort study included individuals diagnosed with CRC between March 13, 2019 and June 20, 2021 across 21 Spanish hospitals. Two time periods were compared: prepandemic (from March 13, 2019 to March 13, 2020) and pandemic (from March 14, 2020 to June 20, 2021, lockdown period and 1 year after lockdown). RESULTS: We observed a 46.9% decrease in the number of CRC diagnoses (95% confidence interval (CI): 45.1%-48.7%) during the lockdown and 29.7% decrease (95% CI: 28.1%-31.4%) in the year after the lockdown. The proportion of patients diagnosed at stage I significantly decreased during the pandemic (21.7% vs. 19.0%; p = 0.025). Centers that applied universal preprocedure SARS-CoV-2 PCR testing experienced a higher reduction in the number of colonoscopies performed during the pandemic post-lockdown (34.0% reduction; 95% CI: 33.6%-34.4% vs. 13.7; 95% CI: 13.4%-13.9%) and in the number of CRCs diagnosed (34.1% reduction; 95% CI: 31.4%-36.8% vs. 26.7%; 95% CI: 24.6%-28.8%). Curative treatment was received by 87.5% of patients diagnosed with rectal cancer prepandemic and 80.7% of patients during the pandemic post-lockdown period (p = 0.002). CONCLUSIONS: The COVID-19 pandemic has led to a decrease in the number of diagnosed CRC cases and in the proportion of stage I CRC. The reduction in the number of colonoscopies and CRC diagnoses was higher in centers that applied universal SARS-CoV-2 PCR screening before colonoscopy. In addition, the COVID-19 pandemic has affected curative treatment of rectal cancers.

Background and study aims In 2019, the European Society of Gastrointestinal Endoscopy (ESGE) created a working group to develop technical and quality standards for small-bowel capsule endoscopy (SBCE) to improve the daily practice of endoscopy services. They developed 10 quality parameters, which have yet to be tested in a real-life setting. Our study aimed to evaluate the accomplishment of the quality standards in SBCE established by the ESGE in several Spanish centers. Materials and methods An online survey of 11 multiple-choice questions related to the ESGE performance measures was sent to Spanish centers with experience in SBCE. In order to participate and obtain reliable data, at least 100 questionnaires had to be answered per center because that is the minimum number established by ESGE. Results 20 centers participated in the study, compiling 2049 SBCEs for the analysis. Only one of 10 performance measures (cecal visualization) reached the minimum standard established by the ESGE. In five of 10 performance measures (Indication, lesion detection rate, terminology, and retention rate) the minimum standard was nearly achieved. Conclusions Our study is the first multicenter study regarding SBCE quality performance measures in a real setting. Our results show that the minimum standard is hardly reached in most procedures, which calls into question their clinical applicability in real life. We suggest performing similar studies in other countries to evaluate whether there is a need for quality improvement programs or a need to reevaluate the minimum and target values published so far.
RESUMEN
Alder decline caused by Phytophthora species is considered one of Europe´s most important diseases of natural ecosystems. In Spain, P. x alni, P. uniformis, P. x multiformis and P. plurivora have been detected in association with root and collar rot in riparian alder populations (Pintos et al. 2010, 2012, 2017; Haque et al. 2014). During the active growth periods 2020-2021, a field survey of the newly designed species Alnus lusitanica (Vít et al. 2017) was carried out at the most symptomatic areas along the Miño-Sil river basin in Galicia and León (NW-Spain). Samples of bark, root, rizosphere soil of declining trees, and river water were collected. Symptoms, similar to those caused by other Phytophthora species, included low leaf density of the canopy, generally with smaller and chlorotic leaves, and branches with dry tips. In some cases, the presence of cankers on the trunk were observed (Figure 1). Necrotic lesions were transferred onto V8-PARPH, a Phytophthora selective medium. Soil and water were baited with carnation petals. Three isolates of one Phytophthora species was recovered: two from the roots of trees, and one from river water at three different sites. The isolates were transferred to V8 agar and incubated a 22ºC in the dark. Colonies had petaloid patterns, and their optimum growth temperature ranged from 25 to 30 °C. In soil extract, non-caducous, non-papillate and ovoid sporangia were produced. Sporangia averaged 41.0×29.4 µm with a length/breadth ratio of 1.39. Internal proliferation occurred (Figure 2). No sexual structures were observed . Genomic DNA was extracted from mycelium obtained from pure cultures of three Phytophthora isolates. The ITS region of the ribosomal DNA template was performed by nested PCR using DC6 (Cooke et al. 2000) and ITS4 (White et al. 1990) in the first round, and ITS6 (Cooke et al. 2000) and ITS4 in the second. The mitochondrial gene cox1 was amplified with primers CoxF4N and CoxR4N (Kroon et al. 2004). BLASTn analyses showed 100% identity to the type of P. lacustris (AF266793, 156 matching bp) for ITS, and 100% identity to the ex-type of P. lacustris (MH136916, 596 matching bp) for the cox1 sequence. Phylogenetic analysis indicated that our isolates were localized in the same evolutionary branch as P. lacustris based on consense sequences of ITS and cox1 sequences. The ITS and cox1 sequences generated in this study were deposited in GenBank with accession number OP588369 and OP548051, and one isolate isolated from root (CECT 21212) was submitted to the Spanish Type Culture Collection (Paterna, Valencia). Pathogenicity tests with isolate CECT 21212 were conducted on ten 3-year-old alders (A. lusitanica) growing in free draining 5 L pots. One shallow cut was made into the cambium at the root collar level. A colonized 5-mm mycelial agar plug, from a 7-day-old culture was inserted into every wound (mycelial surface face-down) and sealed with Parafilm®. Five control plants were inoculated with a sterile agar plug. Plants were kept in a controlled chamber at 25 ºC and 80% humidity. After a 3-week incubation period, inoculated plants showed dieback symptoms and necrosis of the inner bark tissue (Figure 3). Lesion lengths ranged from 2 to 8 cm. Control plants remained symptomless. P. lacustris was recovered from all inoculated plants, but not from the control ones. To our knowledge, this is the first report of P. lacustris causing root rot on alders in Spain. This new detection represents an increased threat to riparian alders by the presence of an additional Phytophthora species associated with alder decline, since P. lacustris can readily adapt to a wide variety of climatic conditions with the ability to infect different hosts (Nechwatal et al. 2013).
RESUMEN
About 60% of the nut production of sweet chestnut (Castanea sativa Mill.) in Europe originates in Spain (FAOSTAT, 2022), mostly (91%) in Galicia (NW Spain). In September 2021, premature fall of immature chestnut burrs and nuts of C. sativa was observed in eight orchards of Pontevedra and Ourense (provinces of Galicia). Chestnut green burrs had turned brown and fallen off, and the nuts showed brown lesions in kernels and embryos. Some nuts had become mummified. Symptomatic samples of burrs and nuts, including mummified fruits, were collected. Small pieces of samples were surface-disinfected with 2% sodium hypochlorite, and plated onto potato dextrose agar (PDA) plates. Colonies were creamy white to gray or light brown, and presented a woolly to felty mycelium with a dense development in concentric circles. Brownish to black conidiomata, produced abundantly, were globose to sub-globose. Conidia were hyaline, oval, obovoid, fusoid and multi-guttulate, and 6.6±0.78 [5.07 to 9.01] µm x 3.2±0.43 [2.41 to 4.38] µm in size. These features matched those described for Gnomoniopsis smithogilvyi (Shuttleworth et al. 2012), syn. G. castaneae (Visentin et al. 2012; Shuttleworth et al. 2015). Genomic DNA was extracted from mycelium developed in 22 burrs and nuts, and 30 pure cultures. The rDNA internal transcribed spacer (ITS), fragments of the ß-tubulin (TUB2) and the translation elongation factor-1α (TEF-1α) genes were amplified using ITS1F (Gardes and Bruns 1993) and ITS4 (White et al. 1990), T1/Bt2b (O'Donnell and Cigelnik 1997), and EF1-728F/EF1-986R (Carbone and Kohn 1999) primers, respectively. Two isolates (EFA 924A, EFA962.4A) were deposited in the Spanish Type Culture Collection (Paterna, Valencia), and their sequences submitted to GenBank (accession nos.: ITS: OM319846, OM319848; TUB2: OM417078, OM417080; TEF-1α: OM417081, OM417083). BLASTn analyses showed: for ITS and TEF-1α sequences, ≥99.7% identity to the ex-type of G. smithogilvyi (ITS: JQ910642, 474 matching bp; TEF-1α: JQ910645, 335-338 matching bp), and for TUB2 sequences, ≥99.1% identity to G. castaneae (LN999975, 446-453 matching bp). Pathogenicity tests were carried out on surface disinfected nuts of Castanea sativa `Raigona´. A superficial wound was made in the pericarp of each nut. A 2-mm mycelial plug of a 7-days-old culture of G. smithogilvyiwas then inoculated: twenty nuts with isolate EFA924A and twenty with isolate EFA962.4A. Twenty nuts inoculated with sterile agar were used as control. The holes were sealed with Parafilm®. Nuts were incubated in a moist chamber at 22±2°C. Two replicated tests were carried out. Four inoculated and four control nuts were inspected for the presence and progress of rot symptoms every seven days. Three weeks after inoculation, all remaining inoculated nuts were completely rotted, whereas all control nuts remained healthy. Gnomoniopsis smitholgilvyi was reisolated from all inoculated nuts, and it was not recovered from the controls. This pathogen causes chestnut brown rot on sweet chestnut worldwide (EPPO, 2022), causing also shoot cankers on chestnut (Lione et al, 2019). This is the first report of G. smithogilvyi causing chestnut brown rot on nuts and burrs of C. sativa in Spain. Future studies on the incidence of this pathogen and its impact on chestnut yield should be carried out in the main European producing countries, i.e. Spain, Italy, Portugal and Greece, where the disease has been detected and represents an emerging threat to chestnut production.
RESUMEN
The fungal endophyte Penicillium olsonii ML37 is a biocontrol agent of Fusarium head blight in wheat (caused by Fusarium graminearum), which has shown a limited direct inhibition of fungal growth in vitro. We used RNA-seq and LC-MS/MS analyses to elucidate metabolic interactions of the three-way system Penicillium-wheat-Fusarium in greenhouse experiments. We demonstrated that P. olsonii ML37 colonises wheat spikes and transiently activates plant defence mechanisms, as pretreated spikes show a faster and stronger expression of the defence metabolism during the first 24 h after pathogen inoculation. This effect was transient and the expression of the same genes was lower in the pathogen-infected spikes than in those infected by P. olsonii alone. This response to the endophyte includes the transcriptional activation of several WRKY transcription factors. This early activation is associated with a reduction in FHB symptoms and significantly lower levels of the F. graminearum metabolites 15-acetyl-DON and culmorin. An increase in the Penicillium-associated metabolite asperphanamate confirms colonisation by the endophyte. Our results suggest that the mode of action used by P. olsonii ML37 is via a local defence activation in wheat spikes, and that this fungus has potential as a novel biological alternative in wheat disease control.
RESUMEN
Our country has achieved one of the highest life expectancies in the world, but this increase has not been matched by a similar growth in healthy life years. Maintaining people's functional capacity as they grow older is essential to provide quality of life for the years they have gained, acting on factors that are modifiable and therefore subject to intervention, such as frailty. This is why it was one of the prioritised interventions in the Prevention and Health Promotion Strategy of the Spanish NHS, which began in 2013. In the collective effort to meet the challenge of addressing frailty, the Autonomous Communities and Cities (AACC) have played a key role in implementing actions on the prevention of frailty and falls in the elderly. The 2019 evaluation of the 3 Consensus document on frailty and falls prevention among the elderly showed very positive data, with high or very high implementation in the AACC. The COVID-19 pandemic has also conditioned the approach to frailty. Frailty has been shown to be a risk factor for the development of illness and death, while COVID-19 has been shown to be a frailty generator. To facilitate the care of the elderly and the approach to frailty, the Ministry of Health, within the EPSP Frailty and Falls Working Group, developed the document of Recommendations for the approach to frailty in the health crisis situation generated by the COVID-19. The future of the approach to frailty in the EPSP is set out in the Roadmap for Addressing Frailty, developed in the framework of the EPSP and the ADVANTAGE Joint Action, which aims to contribute to making frailty a public health priority and to promote its approach at population and individual level, including prevention, early population detection and surveillance/monitoring, from an integrated and coordinated model of care, without forgetting the strengthening of training and research. In the current situation of tension in the socio-health system, which has manifested itself since the COVID-19 crisis, it is necessary to articulate how to continue to provide quality care, not only for the acute situation, but also for other situations such as frailty, care for chronic diseases, geriatric syndromes and physical, mental and social needs. A disability-free life expectancy must be based on the promotion of active and healthy ageing to ensure that older people maintain maximum functional capacity. To this end, it is essential to assess and prevent or reverse frailty, avoiding progression to disability and further overburdening of the system, individuals, families and society as a whole.
Nuestro país ha alcanzado una de las esperanzas de vida más altas del mundo, pero este incremento no se ha acompañado de un crecimiento similar en años de vida en buena salud. Para dotar de calidad de vida los años ganados, es fundamental mantener la capacidad funcional de las personas a medida que envejecen, actuando en factores que son modificables y, por tanto, sujetos a intervención, como la fragilidad. Por ello, ésta fue una de las intervenciones priorizadas en la Estrategia de Promoción de la Salud y Prevención en el SNS (EPSP), que comenzó en el año 2013. En el esfuerzo colectivo por afrontar el reto del abordaje de la fragilidad, las comunidades y ciudades autónomas (CCAA) han tenido un papel fundamental en la implementación de acciones sobre la prevención de la fragilidad y caídas en la persona mayor. La evaluación de 2019 del Documento de consenso sobre prevención de fragilidad y caídas en la persona mayor, arrojó datos muy positivos, con una implementación alta o muy alta en las CCAA. La pandemia de COVID-19, ha condicionado también el abordaje de la fragilidad. Ésta se ha mostrado como un factor de riesgo para el desarrollo de enfermedad y fallecimiento, a la vez que la COVID-19 se ha manifestado como una enfermedad fragilizante. Para facilitar la atención de las personas mayores y el abordaje de la fragilidad desde el Ministerio de Sanidad, en el seno del Grupo de Trabajo de Fragilidad 2 y Caídas de la EPSP, se desarrolló el documento de Recomendaciones para el abordaje de la fragilidad en situación de crisis sanitaria generada por la COVID-19. El futuro del abordaje de la fragilidad en la EPSP está recogido en la Hoja de Ruta para el abordaje de la Fragilidad, elaborada en el marco de la EPSP y de la Acción Conjunta ADVANTAGE, mediante la que se propone contribuir a convertir la fragilidad en una prioridad de salud pública y a promocionar su abordaje a nivel poblacional e individual, incluyendo su prevención, detección precoz poblacional y vigilancia/monitorización, desde un modelo integrado y coordinado de cuidado, sin olvidar el fortalecimiento de la formación e investigación. En la situación actual de tensión del sistema socio-sanitario, que se ha manifestado a partir de la crisis por la COVID-19, es necesario articular cómo continuar prestando una atención de calidad, no solo a la situación aguda, sino también a otras situaciones como la fragilidad, la atención de las enfermedades crónicas, síndromes geriátricos y a las necesidades físicas, mentales y sociales. Una expectativa de vida libre de discapacidad debe basarse en la promoción de un envejecimiento activo y saludable que garantice que las personas mayores mantengan la máxima capacidad funcional. Para ello es fundamental evaluar y prevenir o revertir la fragilidad, evitando la progresión hacia la discapacidad y la mayor sobrecarga del sistema, las personas, familias y la sociedad en su conjunto.

Trichoderma gamsii T6085 has been investigated for many years as a beneficial isolate for use in the biocontrol of Fusarium head blight (FHB) of wheat caused primarily by Fusarium graminearum. Previous work focused on application of T6085 to wheat spikes at anthesis, whereas application to soil before or at sowing has received limited attention. In the present study, the competitive ability of T6085 on plant residues against F. graminearum was investigated. Results showed a significant reduction of wheat straw colonization by the pathogen and of the development of perithecia, not only when T6085 was applied alone but also in the presence of a F. oxysporum isolate (7121), well known as a natural competitor on wheat plant residues. T6085 was able to endophytically colonize wheat roots, resulting in internal colonization of the radical cortex area, without reaching the vascular system, as confirmed by confocal microscopy. This intimate interaction with the plant resulted in a significant increase of the expression of the plant defense-related genes PAL1 and PR1. Taken together, competitive ability, endophytic behavior, and host resistance induction represent three important traits that can be of great use in the application of T6085 against FHB not only on spikes at anthesis but potentially also in soil before or at sowing.

STUDY OBJECTIVES: Consumer wearable devices may be a helpful method of assessing sleep, but validation is required for their use in clinical practice. Our aim was to validate two models of Fitbit sleep trackers that rely on both accelerometer and heart rate sensors against polysomnography in participants with obstructive sleep apnea (OSA). METHODS: Participants were adults presenting with symptoms of OSA and attending our outpatient sleep clinic. A polysomnography (PSG) was applied to all participants at the same time they were wearing a Fitbit sleep tracker. Using paired t tests and Bland-Altman plots, we compared the sleep measures provided by the wearable devices with those obtained by PSG. Since Fitbit devices' automatic detection of sleep start time can cause bias, we performed a correction using Huber loss function-based linear regression and a leave-one-out strategy. RESULTS: Our sample consisted of 65 patients. Diagnosis of OSA was confirmed on 55 (84.6%). There were statistically significant differences between PSG and Fitbit measures for all sleep outcomes but rapid eye movement sleep. Fitbit devices overestimated total sleep time, and underestimated wake after sleep onset and sleep onset latency. After correction of bias, Fitbit-delivered measures of sleep onset latency did not significantly differ of those provided by PSG. CONCLUSIONS: Fitbit wearable devices showed an acceptable sensitivity but poor specificity. Consumer sleep trackers still have insufficient accuracy for clinical settings, especially in clinical populations. Solving technical issues and optimizing clinically-oriented features could make them apt for their use in clinical practice in a nondistant future.

The primary study objective is to compare the outcomes of patients taking oral anticoagulant medications in two distinct populations treated according to different management models (comprehensive vs. usual care). (Design: regional prospective cohort study; setting: hospital admission data from two regions). Eligible partecipants were patients taking oral anticoagulant drugs (vitamin K antagonist or direct oral anticoagulants), residents in the Vicenza and Cremona districts from February 1st, 2016 to June 30th, 2017. Patients were identified by accessing the administrative databases of patient drug prescriptions. The primary study outcome was admission to the Emergency Department for stroke, systemic arterial embolism, recurrence of venous thromboembolism or major bleeding. The study evaluated outcomes in 14,226 patients taking oral anticoagulants, of whom 6725 being followed in Cremona with a comprehensive management model. There were 19 and 45 thromboembolic events over 6205 and 6530 patient-years in the Cremona and Vicenza cohort, respectively (IRR 0.44, 95% CI 0.24-0.77). The reduction of events in the Cremona cohort was almost entirely explained by a decrease of events in patients taking VKA (IRR 0.41, 95% CI 0.20-0.78) but not DOACs (IRR 1.08, 95% CI 0.25-5.24). The rate of major bleeding was non-significantly higher in Cremona than in Vicenza (IRI 1.32; 95% CI 0.74-2.40). Across the two cohorts, the risk of bleeding was lower in patients being treated with DOACs rather than warfarin (10/4574 vs. 42/8161 event/person-years, respectively, IRR 0.42 95% CI 0.19-0.86). We conclude that a comprehensive management model providing centralized dose prescription and follow-up may significantly reduce the rate of thromboembolic complications, without substantially increasing the number of bleeding complications. Patients treated with direct oral anticoagulants appear to have a rate of thromboembolic complications comparable to VKA patients under the best management model, with a reduction of major bleeding.

PURPOSE: The purpose of the study was to compare the safety and efficacy of autologous mesenchymal stem cells (MSCs) embedded in a xenogenic scaffold for repairing the supraspinatus tendon. METHODS: This was a randomized, double-blind and placebo-controlled trial evaluating patients with full-thickness rotator cuff tears (Eudra-CT, 2007-007630-19). Effectiveness was evaluated using the Constant score and a visual analogue pain scale (VAS). Constant score has four domains including pain (15 possible points), activities of daily living (20 possible points), mobility (40 possible points), and strength (25 possible points). Scores range from 0 points (most disability) to 100 points (least disability). The structural integrity of the repaired tendon was assessed by magnetic resonance imaging (MRI) according to Patte and Thomazeau classification criteria. The primary study end point was an improvement in the Constant score by 20 points at one year compared to initial assessment. RESULTS: The trial was stopped due to adverse effects observed in both groups. Only thirteen patients were included and analyzed. The Constant questionnaire showed a significant improvement in the MSC treatment group compared with the preoperative data (p = 0.0073). Secondary outcome measures were similar in both groups. CONCLUSIONS: Our study showed preliminary inconclusive clinical outcomes in the patients treated with MSCs. Adverse events revealed the need for further approaches using scaffolds of a different nature or perhaps no scaffolds, in the context of small joints. TRIAL REGISTRATION: Eudra-CT, 2007-007630-19 . Registered on 30 January 2008. LEVEL OF EVIDENCE: A Level 1 of evidence treatment study.

Trichoderma gamsii T6085 was used in combination with a Fusarium oxysporum isolate (7121) in order to evaluate, in a multitrophic approach, their competitive ability against F. graminearum, one of the main causal agents of Fusarium head blight (FHB) on wheat. The two antagonists and the pathogen were coinoculated on two different natural substrates, wheat and rice kernels. Both T6085 and 7121, alone and coinoculated, significantly reduced the substrate colonization and mycotoxin production by the pathogen. The two antagonists did not affect each other. Using a metabolic approach (Biolog), we investigated whether exploitation competition could explain this antagonistic activity. The aim was to define whether the three fungi coexist or if one isolate nutritionally dominates another. Results obtained from Biolog suggest that no exploitative competition occurs between the antagonists and the pathogen during the colonization of the natural substrates. Interference competition was then preliminarily evaluated to justify the reduction in the pathogen's growth and to better explain mechanisms. A significant reduction of F. graminearum growth was observed when the pathogen grew in the cultural filtrates of T. gamsii T6085, both alone and cocultured with F. oxysporum 7121, thus suggesting the involvement of secondary metabolites. As far as we know, this is the first time that an ecological study has been performed to explain how and which kind of competition could be involved in a multitrophic biocontrol of FHB.

Sleep disturbances and suicidal behaviour are highly prevalent phenomena, representing with a significant burden to society. Sleep has been acknowledged as a potential biomarker for suicidal behaviour. Over the past decade several studies have explored the association between sleep problems and suicidal behaviour. This area has attracted a growing research interest, hence updated information is needed. We therefore present a wide-scope review of the literature summarizing the most relevant studies on epidemiological and theoretical issues underlying this association. Implications of these findings for clinical practice and future research are discussed. We performed a systematic search of PubMed and Embase databases up to October 2018 to identify studies exploring the association between sleep and suicide. Sixty-five articles met the selection criteria, thus they were included in the review. There was a significant and independent association between sleep disturbances and suicide risk. Psychiatric disorders, sleep deprivation-induced neurocognitive deficits, emotional dysregulation, alterations in circadian rhythms, and negative feelings, among other factors, contributed to this relationship. Sleep loss may lead to higher levels of impulsivity, thus increasing unplanned suicidal behaviour. Sleep disturbances may therefore predict suicidal behaviour, hence becoming a potential therapeutic target.

BACKGROUND: Serrated polyposis syndrome (SPS) has been associated with an increased risk of colorectal cancer (CRC). Accordingly, intensive surveillance with annual colonoscopy is advised. The aim of this multicenter study was to describe the risk of advanced lesions in SPS patients undergoing surveillance, and to identify risk factors that could guide the prevention strategy. METHODS: From March 2013 to April 2015, 296 patients who fulfilled criteria I and/or III for SPS were retrospectively recruited at 18 centers. We selected patients in whom successful clearing colonoscopy had been performed and who underwent subsequent endoscopic surveillance. Advanced neoplasia was defined as CRC, advanced adenoma, or advanced serrated lesion that were ≥â10âmm and/or with dysplasia. Cumulative incidence of advanced neoplasia was calculated and independent predictors of advanced neoplasia development were identified. RESULTS: In 152 SPS patients a total of 315 surveillance colonoscopies were performed (median 2, range 1â-â7). The 3-year cumulative incidence of CRC and advanced neoplasia were 3.1â% (95â% confidence interval [CI] 0â-â6.9) and 42.0â% (95â%CI 32.4â-â51.7), respectively. Fulfilling both Iâ+âIII criteria and the presence of advanced serrated lesions at baseline colonoscopy were independent predictors of advanced neoplasia development (odds ratio [OR] 1.85, 95â%CI 1.03â-â3.33, P â=â0.04 and OR 2.62, 95â%CI 1.18â-â5.81, P â=â0.02, respectively). During follow-up, nine patients (5.9â%) were referred for surgery for invasive CRC (nâ=â4, 2.6â%) or because of polyp burden (nâ=â5, 3.3â%). After total colectomy, 17.9â% patients developed advanced neoplasia in the retained rectum. CONCLUSIONS: Patients with SPS have a substantial risk of developing advanced neoplasia under endoscopic surveillance, whereas CRC incidence is low. Personalized endoscopic surveillance based on polyp burden and advanced serrated histology could help to optimize prevention in patients with SPS.

En el marco de la Estrategia de Promoción de la Salud y Prevención en el Sistema Nacional de Salud, la implementación local es una de las líneas consideradas prioritarias. Dicha implementación propone la adhesión voluntaria de las entidades locales para trabajar en promoción de la salud y prevención mediante la realización de dos acciones: la constitución de una mesa de coordinación intersectorial y la identificación de recursos para la promoción de la salud y la prevención en el municipio. La Guía para la Implementación Local de la Estrategia fue aprobada en 2015 por el Consejo Interterritorial del Sistema Nacional de Salud. A fecha de junio de 2018, se han adherido a ella 261 entidades locales, se han identificado 7072 recursos y 9183 actividades, y se han creado 132 mesas intersectoriales

Double balloon enteroscopy (DBE) is an endoscopic technique broadly used to diagnose and treat small bowel diseases. Among the associated complications of the oral DBE, post-procedure pancreatitis has taken the most attention due to its gravity and the thought that it might be associated to the technique itself and anatomical features of the pancreas. However, as the etiology has not been clarified yet, this paper aims to review the published literature and adds new results from a porcine animal model. Biochemical markers, histological sections and the vascular perfusion of the pancreas were monitored in the pig during DBE practice. A reduced perfusion of the pancreas and bowel, the presence of defined hypoxic areas and disseminated necrotic zones were found in the pancreatic tissue of pigs. All these evidences contribute to support a vascular distress as the most likely etiology of the post-DBE pancreatitis.
