How perceived maternal gatekeeping affects fathers: An 8-week study.

Maternal gatekeeping describes mothers' attempts to influence father involvement in child-rearing. While the effect of maternal gatekeeping on the father-child relationship has been explored, less is known about how fluctuations in the perception of maternal gatekeeping influences fathers' family outcomes and whether father's attachment might moderate these associations. Building on family systems theory, this study explores the within-person effect of negative maternal gatekeeping on father's weekly reports of romantic relationship quality and feelings of exclusion from the family and tests father attachment as a moderator of these associations. Two hundred seventy-seven Canadian and German fathers with children under the age of 6 took part in an 8-week online diary study. Data were analyzed using multilevel structural equation modeling. During weeks when fathers perceived more maternal gatekeeping than was typical, they reported lower positive romantic relationship quality, higher negative romantic relationship quality, and felt more excluded from the family system. Avoidant attachment moderated the within-person effect of perceived maternal gatekeeping on negative romantic relationship quality, such that within-person increases in perceived maternal gatekeeping were more strongly linked with higher than-average negative romantic relationship quality among more avoidant fathers. Our findings shed new light on the within-person effects of perceived maternal gatekeeping on fathers' feelings regarding the family system.

Determinants of diversity and composition of the tapeworm fauna of blue sharks, Prionace glauca: a geographical and host-specificity analysis.

Blue sharks, Prionace glauca, are cosmopolitan, extremely vagile sharks and the species among elasmobranchs for which most surveys containing tapeworm community data are available worldwide. In this study we report on the tapeworm fauna of three samples of blue sharks (n = 37) from two new regions (one sample from Galicia, north-east Atlantic, and two from Valencia, western Mediterranean), and compared it with previous studies, assessing the relative role of the ecological and evolutionary factors in structuring local tapeworm assemblages. Nine cestode taxa were identified, of which four included adult specimens, that is, Platybothrium auriculatum, Prosobothrium armigerum, Anthobothrium caseyi and Molicola horridus. The abundance of these species, and Brillouin's diversity index, differed significantly among samples without a clear geographical signal. A comparison with six previous surveys revealed that tapeworm assemblages were composed of the same 'core' taxa, with mean species richness typically ranging from two to four species. Global records of adult tapeworms in blue sharks included: 15 taxa identified at species level, of which only eight (generalist trypanorhynchs) were shared with other sympatric host species; five mostly with other carcharhinids; and three with large lamnid sharks sharing the blue sharks' habitat. The composition of tapeworm communities of blue sharks is thus highly constrained by strong host specificity, with composition and abundance varying across localities depending on idiosyncratic environmental conditions.

Characterization of the contamination fingerprint of wastewater treatment plant effluents in the Henares River Basin (central Spain) based on target and suspect screening analysis.

The interest in contaminants of emerging concern (CECs) has increased lately due to their continued emission and potential ecotoxicological hazards. Wastewater treatment plants (WWTPs) are generally not capable of eliminating them and are considered the main pathway for CECs to the aquatic environment. The number of CECs in WWTPs effluents is often so large that complementary approaches to the conventional target analysis need to be implemented. Within this context, multitarget quantitative analysis (162 compounds) and a suspect screening (>40,000 suspects) approaches were applied to characterize the CEC fingerprint in effluents of five WWTPs in the Henares River basin (central Spain) during two sampling campaigns (summer and autumn). The results indicated that 76% of the compounds quantified corresponded to pharmaceuticals, 21% to pesticides and 3% to industrial chemicals. Apart from the 82 compounds quantified, suspect screening increased the list to 297 annotated compounds. Significant differences in the CEC fingerprint were observed between summer and autumn campaigns and between the WWTPs, being those serving the city of Alcalá de Henares the ones with the largest number of compounds and concentrations. Finally, a risk prioritization approach was applied based on risk quotients (RQs) for algae, invertebrates, and fish. Azithromycin, diuron, chlortoluron, clarithromycin, sertraline and sulfamethoxazole were identified as having the largest risks to algae. As for invertebrates, the compounds having the largest RQs were carbendazim, fenoxycarb and eprosartan, and for fish acetaminophen, DEET, carbendazim, caffeine, fluconazole, and azithromycin. The two WWTPs showing higher calculated Risk Indexes had tertiary treatments, which points towards the need of increasing the removal efficiency in urban WWTPs. Furthermore, considering the complex mixtures emitted into the environment and the low dilution capacity of Mediterranean rivers, we recommend the development of detailed monitoring plans and stricter regulations to control the chemical burden created to freshwater ecosystems.

Mechanical characterisation of hydrophobic and hydrophilic acrylates used in intraocular lenses through depth sensing indentation.

In this work, the mechanical behaviour of hydrophilic and hydrophobic acrylates has been characterised by depth sensing indentation. Time-dependent behaviour has been studied using load-relaxation tests. Experiments have been simulated with a finite element software using a visco-hyperelastic material model. The parameters of this model have been determined using deep learning techniques. The developed material models have been used to mechanically simulate a standard compression test of a prototype intraocular lens.

Prevalence and Characterization of Urinary Tract Infection in Owned Dogs and Cats From Spain.

Bacterial urinary tract infection (UTI) is a common clinical concern in dogs. However, incidence of feline UTI is much lower than in dogs although an increasing prevalence has been registered. The main objective of the present study was to describe and characterize the prevalence of urinary tract pathogens in urine samples of dogs and cats with urinary clinical signs throughout different Spanish provinces. Secondary aims were to determine if there were differences in urine sample characterizations based on species (i.e., dog and cat) or season. Dogs were found to have a higher rate of positive urinary cultures than cats (39.3% and 24.7% of the cultures submitted, respectively). The bacterial genera most commonly isolated in dogs were Escherichia spp. (45.3%), Proteus spp. (13.2%), Staphylococcus spp. (11%), and Enterococcus spp. (8.6%). Whereas in the feline population, Escherichia spp. (42.7%), Enterococcus spp. (22.2%), and Staphyloccoccus spp. (15.2%) were the most frequently isolated bacteria. The highest rates of positive urine cultures were registered in Melilla (70%), Zamora (66.7%), Teruel (64.3%), and Guadalajara (60%). Moreover, the proportion of positive urine cultures was not homogeneously distributed across provinces. Finally, some seasonality was found among most isolated bacterias. Enterococcus spp. was significantly more prevalent in summer, whereas Escherichia spp. and Proteus spp. were more commonly isolated in spring and Pseudomonas spp. in autumn.

Management of isolated mandibular body fractures in adults

Objective@#The mandible is the most common fractured craniofacial bone of all craniofacial fractures in the Philippines, with the mandibular body as the most involved segment of all mandibular fractures. To the best of our knowledge, there are no existing guidelines for the diagnosis and management of mandibular body fractures in particular. General guidelines include the American Academy of Otolaryngology – Head and Neck Surgery Foundation (AAOHNSF) Resident Manual of Trauma to the Face, Head, and Neck chapter on Mandibular Trauma, the American Association of Oral and Maxillofacial Surgeons (AAOMS) Clinical Practice Guidelines for Oral and Maxillofacial Surgery section on the Mandibular Angle, Body, and Ramus, and a 2013 Cochrane Systematic Review on interventions for the management of mandibular fractures. On the other hand, a very specific Clinical Practice Guideline on the Management of Unilateral Condylar Fracture of the Mandible was published by the Ministry of Health Malaysia in 2005. Addressing the prevalence of mandibular body fractures, and dearth of specific guidelines for its diagnosis and management, this clinical practice guideline focuses on the management of isolated mandibular body fractures in adults.@*Purpose@#This guideline is meant for all clinicians (otolaryngologists – head and neck surgeons, as well as primary care and specialist physicians, nurses and nurse practitioners, midwives and community health workers, dentists, and emergency first-responders) who may provide care to adults aged 18 years and above that may present with an acute history and physical and/or laboratory examination findings that may lead to a diagnosis of isolated mandibular body fracture and its subsequent medical and surgical management, including health promotion and disease prevention. It is applicable in any setting (including urban and rural primary-care, community centers, treatment units, hospital emergency rooms, operating rooms) in which adults with isolated mandibular body fractures would be identified, diagnosed, or managed. Outcomes are functional resolution of isolated mandibular body fractures; achieving premorbid form; avoiding use of context-inappropriate diagnostics and therapeutics; minimizing use of ineffective interventions; avoiding co-morbid infections, conditions, complications and adverse events; minimizing cost; maximizing health-related quality of life of individuals with isolated mandibular body fracture; increasing patient satisfaction; and preventing recurrence in patients and occurrence in others.@*Action Statements@#The guideline development group made strong recommendationsfor the following key action statements: (6) pain management- clinicians should routinely evaluate pain in patients with isolated mandibular body fractures using a numerical rating scale (NRS) or visual analog scale (VAS); analgesics should be routinely offered to patients with a numerical rating pain scale score or VAS of at least 4/10 (paracetamol and a mild opioid with or without an adjuvant analgesic) until the numerical rating pain scale score or VAS is 3/10 at most; (7) antibiotics- prophylactic antibiotics should be given to adult patients with isolated mandibular body fractures with concomitant mucosal or skin opening with or without direct visualization of bone fragments; penicillin is the drug of choice while clindamycin may be used as an alternative; and (14) prevention- clinicians should advocate for compliance with road traffic safety laws (speed limit, anti-drunk driving, seatbelt and helmet use) for the prevention of motor vehicle, cycling and pedestrian accidents and maxillofacial injuries.The guideline development group made recommendations for the following key action statements: (1) history, clinical presentation, and diagnosis - clinicians should consider a presumptive diagnosis of mandibular fracture in adults presenting with a history of traumatic injury to the jaw plus a positive tongue blade test, and any of the following: malocclusion, trismus, tenderness on jaw closure and broken tooth; (2) panoramic x-ray - clinicians may request for panoramic x-ray as the initial imaging tool in evaluating patients with a presumptive clinical diagnosis; (3) radiographs - where panoramic radiography is not available, clinicians may recommend plain mandibular radiography; (4) computed tomography - if available, non-contrast facial CT Scan may be obtained; (5) immobilization - fractures should be temporarily immobilized/splinted with a figure-of-eight bandage until definitive surgical management can be performed or while initiating transport during emergency situations; (8) anesthesia - nasotracheal intubation is the preferred route of anesthesia; in the presence of contraindications, submental intubation or tracheostomy may be performed; (9) observation - with a soft diet may serve as management for favorable isolated nondisplaced and nonmobile mandibular body fractures with unchanged pre - traumatic occlusion; (10) closed reduction - with immobilization by maxillomandibular fixation for 4-6 weeks may be considered for minimally displaced favorable isolated mandibular body fractures with stable dentition, good nutrition and willingness to comply with post-procedure care that may affect oral hygiene, diet modifications, appearance, oral health and functional concerns (eating, swallowing and speech); (11) open reduction with transosseous wiring - with MMF is an option for isolated displaced unfavorable and unstable mandibular body fracture patients who cannot afford or avail of titanium plates; (12) open reduction with titanium plates - ORIF using titanium plates and screws should be performed in isolated displaced unfavorable and unstable mandibular body fracture; (13) maxillomandibular fixation - intraoperative MMF may not be routinely needed prior to reduction and internal fixation; and (15) promotion - clinicians should play a positive role in the prevention of interpersonal and collective violence as well as the settings in which violence occurs in order to avoid injuries in general and mandibular fractures in particular.

[Inbreeding and serious mental illness in the first Spanish Bourbons]. / Consanguinidad y enfermedad mental grave en los primeros Borbones españoles.

INTRODUCTION: There is an argument about inbreeding as a risk factor in the development of major mental illnesses like bipolar disorder or schizophrenia. The genealogical trees of European royal dynasties represent an opportunity to study this relationship. Felipe V was the first Bourbon king to rule in Spain, who was thought to have possibly suffered a severe mental disorder. Felipe's son Fernando VI, also had a mental disease. Nevertheless Carlos III, Felipe V's son born from a different, unrelated mother, apparently showed no trace of such disorder. We hypothesize that consanguinity or inbreeding could explain the tendency in the acquiring of severe mental disorders. SUBJECTS AND METHODS:  Biographies of three Spanish Bourbon kings (Felipe V, Fernando VI and Carlos III) were analysed in order to evaluate if they were likely to have suffered from some mental disorder, according to DSM-5 and ICD-11 criteria. An inbreeding coefficient was determined with the PedPro Program. RESULTS:  Felipe V and Fernando VI could have been diagnosed with bipolar disorder, whereas Carlos III could have been diagnosed with a mild personality disorder. Both Felipe V and Fernando VI had a high inbreeding coefficient (0.091109 and 0.095023, respectively), while Carlos III had a lower one (0.038264). The inbreeding coefficient of siblings of couples of first grade cousins is 0.0625. CONCLUSIONS:  A high inbreeding coefficient is a risk factor in developing bipolar disorder. Felipe V and Fernando VI suffered from bipolar disorder. The analysis of genetic trees by the inbreeding coefficient is a valuable tool in the study of heredability of bipolar disorder. Endogamy accumulates pathogenic alleles and increases risk to suffer it. These kings had a high consanguinity which was an important risk factor to the illness. High consanguinity is a risk factor to suffer bipolar disorder.

TITLE: Consanguinidad y enfermedad mental grave en los primeros Borbones españoles.Introducción. Se discute si la consanguinidad es un factor de riesgo para sufrir trastorno bipolar o esquizofrenia. Los árboles genealógicos de las casas reales son una oportunidad para estudiarlo. Felipe V posiblemente sufrió un trastorno mental grave, como también su hijo Fernando VI. Sin embargo, Carlos III, también hijo de Felipe V, pero fruto de otro matrimonio, aparentemente no. Se mantiene la hipótesis de que la consanguinidad podría haber sido un factor de riesgo para ello. Sujetos y métodos. Se analizan las biografías de estos tres reyes para detectar si sufrieron algún trastorno mental de acuerdo con el DSM-5 y la CIE-11. Se estudia su coeficiente de consanguinidad mediante el programa PedPro con una base de datos de 25.776 individuos. Resultados. Felipe V y Fernando VI podrían haber sido diagnosticados de trastorno bipolar, mientras que Carlos III podría haberlo sido de un leve trastorno de la personalidad. Felipe V y Fernando VI tenían un coeficiente de consanguinidad elevado (0,091109 y 0,095023, respectivamente), mientras que en Carlos III era sólo de 0,038264. El coeficiente de los dos primeros es mayor que el de los hijos de primos hermanos (0,0625). Conclusiones. Felipe V y Fernando VI sufrieron un trastorno bipolar. El análisis de los árboles genéticos mediante el coeficiente de consanguinidad es una valiosa herramienta para el estudio de la heredabilidad del trastorno bipolar. La endogamia acumula alelos patógenos y el riesgo de sufrirlo. En estos sujetos, la alta consanguinidad fue un importante factor etiopatogénico de la enfermedad que sufrieron. Una elevada consanguinidad supone un factor de riesgo de sufrir trastorno bipolar.

El análisis de aguas residuales con fines epidemiológicos: presente y futuro en España / Wastewater-based epidemiology: present and future in Spain

El análisis de aguas residuales con fines epidemiológicos es actualmente una herramienta fiable y complementaria a las metodologías basadas en indicadores tradicionales para el control de diferentes sustancias entre las que cabe destacar las drogas. Si bien varios países europeos la utilizan como herramienta de trabajo para la monitorización de drogas de abuso, en España su uso se limita principalmente a estudios realizados por diferentes grupos de investigación, tal y como se describe en el caso práctico puesto de ejemplo en el artículo. Sin embargo, el potencial de la metodología ha quedado evidenciado en los estudios científicos llevados a cabo tanto a nivel español como internacional y, aunque son necesarios más estudios para llegar a conocer todo su potencial, se prevé pueda ser incorporada como herramienta de trabajo complementaria a las que habitualmente se utilizan. En este sentido, la Red Española de Análisis de Aguas Residuales (ESAR-Net), creada en 2017 y formada por diferentes grupos de investigación españoles, pretende contribuir al conocimiento y aplicación de esta metodología en España a través de actividades científicas y de divulgación

Wastewater-Based Epidemiology is currently a reliable and complementary tool to methodologies based on traditional indicators for the control of various substances such as drugs. Although several European countries use it as a working tool for the monitoring of drugs of abuse, in Spain its use is mainly limited to studies carried out by different research groups, as described in the case study used as an example in the article. However, the potential of the methodology has been demonstrated in the scientific studies carried out both at the Spanish and international level and, although more studies are necessary to get to know its full potential, it is expected that it could be incorporated as a complementary work tool to those that are usually used. In this sense, the Red Española de Análisis de Aguas Residuales (ESAR-Net), created in 2017 and formed by different Spanish research groups, aims to contribute to the knowledge and application of this methodology in Spain through scientific and outreach activities

Ocorrência de ectoparasitas no roedor Oligoryzomys microtis em regiões ao norte do Departamento de La Paz, Bolívia / Occurrence of ectoparasites in rodents of the species Oligoryzomys microtis in northern La Paz Department, Bolivia

O objetivo deste trabalho foi mapear e descrever a ocorrência de roedores e seus ectoparasitas nas regiões norte do departamento de La Paz, Bolívia. De abril a maio e julho a agosto de 2017, 80 indivíduos da espécie Oligoryzomys microtis foram capturados em armadilhas vivas. Uma amostra aleatória de 36 indivíduos foi analisada quanto à presença de ectoparasitas, encontrando um total de 458 ectoparasitas. Os roedores foram capturados em dois tipos de ambientes: floresta secundária e áreas cultivadas, sendo a área cultivada a área com maior captação de roedores. Dos ectoparasitas, Laelaps sp. foi o gênero com maior abundância e Mysolaelaps sp. o mais prevalente; o gênero Polygenis sp. é aparentemente descrito pela primeira vez na selva amazônica, exigindo estudos adicionais para entender melhor os patógenos que são transmitidos no parasitismo desta pulga em roedores devido à sua importância no ecossistema e para a saúde pública.(AU)

The objective of this work was to map and describe the occurrence of rodents and their ectoparasites in regions to the North of the department of La Paz in Bolivia. From April to May and July to August 2017, 80 Oligoryzomys microtis rodents were captured and 36 random samples of their ectoparasites were analyzed, totaling 458 ectoparasites. Rodents were captured in two types of environments: secondary forest and crops areas, being the second one with greater amount of capture of rodents. Among the ectoparasites, Laelaps sp was the genus with the highest abundance and Mysolaelaps sp with the highest prevalence; the genus Polygenis sp is apparently described for the first time in the Amazon rainforest, requiring more studies to better understand the pathogens transmitted in the parasitism of this flea in rodents due to their importance in the ecosystem and public health.(AU)

Suppressive antibiotic therapy in prosthetic joint infections: a multicentre cohort study.

OBJECTIVES: The aim was to describe the effectiveness of suppressive antibiotic treatment (SAT) in routine clinical practice when used in situations in which removal of a prosthetic implant is considered essential for the eradication of an infection, and it cannot be performed. METHODS: This was a descriptive retrospective and multicentre cohort study of prosthetic joint infection (PJI) cases managed with SAT. SAT was considered to have failed if a fistula appeared or persisted, if debridement was necessary, if the prosthesis was removed due to persistence of the infection or if uncontrolled symptoms were present. RESULTS: In total, 302 patients were analysed. Two hundred and three of these patients (67.2%) received monotherapy. The most commonly used drugs were tetracyclines (39.7% of patients) (120/302) and cotrimoxazole (35.4% of patients) (107/302). SAT was considered successful in 58.6% (177/302) of the patients (median time administered, 36.5 months; IQR 20.75-59.25). Infection was controlled in 50% of patients at 5 years according to Kaplan-Meier analysis. Resistance development was documented in 15 of 65 (23.1%) of the microbiologically documented cases. SAT failure was associated with age <70 years (sub-hazard ratio (SHR) 1.61, 95% CI 1.1-2.33), aetiology other than Gram-positive cocci (SHR 1.56, 95% CI 1.09-2.27) and location of the prosthesis in the upper limb (SHR 2.4, 95% CI 1.5-3.84). SAT suspension was necessary due to adverse effects in 17 of 302 patients (5.6%). CONCLUSIONS: SAT offers acceptable results for patients with PJI when surgical treatment is not performed or when it fails to eradicate the infection.

Factores pronósticos y análisis de la mortalidad de las hemorragias cerebrales asociadas a anticoagulantes orales antagonistas de la vitamina K. Resultados del Estudio TAC Registry / Prognostic factors and analysis of mortality due to brain haemorrhages associated with vitamin K antagonist oral anticoagulants. Results from the TAC registry

INTRODUCCIÓN: La hemorragia intracraneal (HIC) en pacientes tratados con anticoagulantes orales antagonistas de la vitamina K (AVK) es una complicación grave y frecuentemente letal; en este trabajo estudiamos las características clínicas y los factores que se relacionan con la mortalidad en este grupo de pacientes. MÉTODOS: Realizamos un estudio observacional, multicéntrico y retrospectivo, de ámbito nacional, basado en registros prospectivos de pacientes con ictus. Se incluyó a los pacientes ingresados en servicios de Neurología durante un período de un año y que cumplieran los criterios de inclusión: pacientes mayores de 18 años con HIC que estuvieran en tratamiento con AVK y que ingresaron durante el periodo de estudio. Se analizaron las variables clínicas y radiológicas y su evolución a 3 meses. RESULTADOS: Incluimos a 235 pacientes provenientes de 21 hospitales. La mortalidad a los 90 días fue del 42,6%. En el modelo bivariante los factores asociados con defunción fueron: mediana en la puntuación de la escala NIHSS al ingreso (5 (RIQ = 9) vs. 17 (RIQ = 14) puntos, p < 0,01) y la presencia de una hemorragia hemisférica extensa (4,9% vs. 35%, p < 0,01; chi2). Las hemorragias hemisféricas extensas, además de ser las más letales, también presentaron el tiempo más corto hasta el fallecimiento (media 16,5 días; IC del 95%, 7,1-26). Realizamos un modelo de regresión logística que evidenció que solo la NIHSS basal predijo de forma independiente el fallecimiento (odds ratio = 1,13 (IC del 95%, 1,0-1,17) por cada punto en la escala). CONCLUSIÓN: La HIC en pacientes tratados con AVK conlleva una elevada mortalidad asociada principal e independientemente con la situación clínica al inicio del ictus

INTRODUCTION: Intracranial haemorrhages (ICH) represent a severe and frequently lethal complication in patients treated with vitamin K antagonists (VKA). The purpose of our study is to describe the factors and clinical features associated with mortality in these patients. METHODS: We conducted an observational, retrospective, multi-centre study based on prospective stroke registries in Spain. We included all patients admitted to neurology departments during a one-year period who met the following inclusion criteria: being 18 or older, having a diagnosis of ICH, and receiving VKA. Clinical and radiological parameters and 3-month outcomes were analysed. RESULTS: A total of 235 patients from 21 hospitals were included. Mortality rate at 90 days was 42.6%. Bivariate analysis showed a significant association between death and the following factors: median NIHSS score at admission (5 (IQR = 9) vs 17 (IQR = 14) points, P < .01) and presence of an extensive hemispheric haemorrhage (4.9% vs 35%, P < .01; chi2). Extensive hemispheric haemorrhages, in addition to being the most lethal type, were associated with a shorter time to death (mean of 16.5 days; 95% CI: 7.1-26). A logistic regression model showed that only baseline NIHSS scores independently predicted death (odds ratio = 1.13 (95% CI: 1.08-1.17) for each point in the scale). CONCLUSION: ICH in patients treated with VKA is associated with high mortality rates; mortality in these patients is mainly and independently associated with the clinical situation at stroke onset

How much progress has there been in the second-line treatment of multiple sclerosis: A 2017 update.

In 1993, the US Food and Drug Administration (FDA) approved the first drug specifically for treating multiple sclerosis (MS). More than two decades later, a dozen such treatments are now available. Of these, four are considered second-line treatments for use in escalation strategies and two new drugs are currently undergoing accreditation procedures. Soon, they will provide clinicians with a range of six effective disease-modifying treatments (DMTs) to thwart the inflammatory processes in MS patients with active disease. However, while such a large number of DMTs for MS can help to control early inflammation, any decisions to be made by clinicians have also been made substantially more complex. This complexity is increased by the lack of head-to-head studies comparing these second-line therapies and the benefit-risk profiles for each of these drugs, which are likely to vary among patients. Ultimately, good awareness of the benefits and, more important, the risks of each MS DMT is crucial for the effective management of inflammation in MS.

Shorter specialist time intervals are associated with advanced stage on symptomatic oral cancer.

OBJECTIVES: As longer times from the first symptom to diagnosis and treatment of oral cancers have been linked to poorer outcomes, this study investigates the contribution of the specialist to this time (STI). SUBJECTS AND METHODS: A series of 228 oral/oropharyngeal squamous cell carcinoma patients were retrospectively studied to determine the STI and its related factors. RESULTS: Patients were mostly males (n = 170; 74.5%), (50.7% stages I-II), mean age = 61.4 ± 12.5 years. The STI median was 6 days (X±SD:6.8 ± 5.6 days). Time first symptom to diagnosis was 64 days (X±SD:91.0 ± 84.6 days). Univariate regression unveiled a significant association between STI and TNM stage, which was confirmed by multivariate regression. CONCLUSIONS: Specialist time interval is a short time interval in oral cancer diagnosis, imposing a limited time burden in the context of the whole interval until diagnosis. However, there seems to be room for improvement and a possible target for future interventions to shorten STI particularly for patients at early stages after their disease has been disclosed.

Reconciling monitoring and modeling: An appraisal of river monitoring networks based on a spatial autocorrelation approach - emerging pollutants in the Danube River as a case study.

Rivers extend in space and time under the influence of their catchment area. Our perception largely relies on discrete spatial and temporal observations carried out at certain sites located throughout the catchment (monitoring networks, MN). However, MNs are constrained by (a) the distribution of sampling sites, (b) the dynamics of the variable considered and (c) the river hydrological conditions. In this study, all three aspects were captured and quantified by applying a spatial autocorrelation modeling approach. We exemplarily studied its application to 235 emerging contaminants (pesticides, pharmaceuticals, and personal care products [PPCP], industrial and miscellaneous) measured at 55 sampling sites in the Danube River. 22 out of the 235 compounds monitored were present at all sites and 125 were found in at least 50%.We first calculated the Moran Index (MI) to characterize the spatial autocorrelation of the compound set. 59 compounds showed MI≤0, which can be interpreted as 'no spatial correlation'. Next, spatial autocorrelation models were set for each compound. From the autocorrelation parameter ρ, catchment average correlation lengths were derived for each compound. MN optimality was examined and compounds were classified into three groups: (a) those with ρ≤0 [25%]; (b) those with ρ>0 and correl. length0 and correl. length>average distance between consecutive sites [73%]. The MN was considered optimal only for the latter class. Networks with the larger average distance between consecutive sites resulted in a decreasing number of optimally monitored compounds. Furthermore, neighbors vs. local relative contributions were quantified based on the spatial autocorrelation model for all the measured compounds. The results of this study show how autocorrelation models can aid water managers to improve the design of river MNs, which are a key aspect of the Water Framework Directive.
