PSIXPORT: Mobile App for Ecological Momentary Assessment of Psychological Dimensions in Sport Injury.

Front Psychol 2021 27;12:697293. Epub 2021 Jul 27.

Psychobiology and Behavioural Sciences' Methodology Department, School of Psychology, University Complutense of Madrid, Madrid, Spain.

Retrospective self-reports have been commonly used to assess psychological variables such as feelings, thoughts, or emotions. Nevertheless, this method presents serious limitations to gather accurate information about variables that change over time. The Ecological Momentary Assessment (EMA) approach has been used to deal with some of the limitations these retrospective assessment methods present, and for gathering real-time information about dynamic psychological variables, such as feelings, thoughts, or behaviors. In the sports injury rehabilitation context, athletes' thoughts, feelings, behaviors, and pain perceptions during the rehabilitation process can influence the outcomes of this process. These responses change over different stages of the rehabilitation and taking them into account can help therapists to adapt the rehabilitation process and increasing their effectiveness. With this aim, an EMA mobile app (PSIXPORT) was designed to gather real-time information about severely injured athletes' cognitive appraisals, emotional responses, behaviors, and pain perceptions during their rehabilitation process. The goals of this study were to evaluate Psixport's ability to gather real-time information about injured athletes' psychological responses during the rehabilitation, to test the users' perceived usability of Psixport, and to compare the reliability and differences between real-time data gathered with Psixport and the data gathered through the one-time retrospective method. Twenty-eight severely injured athletes (10 men and 18 women) were assessed using Psixport, a retrospective questionnaire, and the uMARS usability test. Results showed that Psixport can be considered as a good tool to gather information about injured athletes' cognitive appraisals, emotional responses, behaviors, and pain perceptions. Moreover, multiple data assessments gathered with the app showed to be more accurate information about injured athletes' psychological responses than one-time retrospective reports.

Athletes' Psychological Adaptation to Confinement Due to COVID-19: A Longitudinal Study.

Front Psychol 2020 14;11:613495. Epub 2021 Jan 14.

Sport Psychology Unit, Center for Applied Psychology, Universidad Autónoma de Madrid, Madrid, Spain.

Studies of individuals under conditions of confinement or severe social and physical restrictions have consistently shown deleterious mental health effects but also high levels of adaptability when dealing with such conditions. Considering the role of physical activity and sport in psychological adaptation, this paper describes a longitudinal study to explore to what extent the imposed restrictions due to the outbreak of SARS-CoV-2 may have affected athletes' mental health outcomes and how far the process of adaptation to confinement conditions is differentially affected depending on whether the sports activity was practiced individually or in a group, and outdoors, indoors, or both. Two hundred and seventy-four athletes were assessed over 7 weeks using the GHQ-28 and an survey exploring the practice of physical activity. A mixed-model fixed effects ANCOVA was used to analyze the effects of time, place, and company in which the sport was practiced, with an index of the amount of physical activity expended as a covariate. Results show a significant effect of time in three out of four of the GHQ-28 subscales, in all cases showing a consistent adaptation to conditions over time. Results also show that playing sport indoors, outdoors, or both, and practicing alone vs. with others differentially affect the somatic symptoms exhibited during confinement: Athletes who practiced sport with others showed higher levels of somatic symptoms at the beginning of the set of data but a quicker rate of adaptation. Differences arising from practicing sport alone or with others were more pronounced in the case of indoor sports, which could be related to the fact that physical activity that can be practiced during confinement is more similar to that practiced indoors alone. Implications relating to what sport psychologists and other health professionals may offer to athletes in stressful situations are discussed.

Nosocomial SARS-CoV-2 infection in urology departments: Results of a prospective multicentric study.

Int J Urol 2021 01 13;28(1):62-67. Epub 2020 Oct 13.

Urology Department, Fundación Jiménez Díaz University Hospital Health Research Institute, Rey Juan Carlos University Hospital, Madrid, Spain.

Objective: To evaluate the coronavirus disease 2019 perioperative infection rate and mortality rate of patients undergoing urological surgeries during the early pandemic period in Spain.

Methods: This was a non-interventional multicenter prospective study carried out from 9 March to 3 May 2020 in two urology departments in Madrid, Spain. Clinical, microbiological and radiological data of patients who underwent surgery were collected from computerized medical records.

Results: A total of 148 patients were included in the study, and 141 were analyzed for nosocomial infection risk, after excluding previous and concomitant severe acute respiratory syndrome coronavirus type 2 infections. Elective surgeries represented 76.6% of the procedures, whereas emergent surgeries represented 23.4%. Preoperative screening was carried out with polymerase chain reaction test in 34 patients, all were negative. A total of 14 patients also had chest X-ray (not suspicious in all cases). Three patients (2.1%) developed severe acute respiratory syndrome coronavirus type 2 nosocomial infection (symptoms developed between the third day after surgery to the 14th day after hospital discharge). Time from admission to a compatible clinical case was 5.5 days (4-12 days). Two patients underwent surgery with concomitant diagnosis of coronavirus disease. The mortality rate due to severe acute respiratory syndrome coronavirus type 2 infection is 0.7%, and the specific mortality rate in patients undergoing surgery with community-acquired coronavirus disease 2019 infection was 50% (1/2).

Conclusions: The nosocomial severe acute respiratory syndrome coronavirus type 2 infection rate was low in patients undergoing urological surgical procedures during the peak of the pandemic in Madrid. With appropriate perioperative screening, urological surgical activity can be carried out in safety conditions.

Understanding the dimensions of sport-injury related growth: A DELPHI method approach.

PLoS One 2020 23;15(6):e0235149. Epub 2020 Jun 23.

Department of Personality, Evaluation and Psychological Treatment, University of Murcia, Murcia, Spain.

Despite the multitude of adverse physical and psychosocial consequences of sports injury, evidence also highlights the potential for positive benefits in the injury aftermath. The purpose of this study is to address this gap by exploring the dimensions of personal growth following a severe sports injury. A 3-rounds e-Delphi method was utilized to develop a consensual understanding of the dimensions of sport-injury related growth. A panel of 24 psychology of sport injury experts participated in the process. The final list of items obtained was subjected to conventional content analysis to identify general themes. The process led to the development of a 5-dimension model capable of describing athletes' experiences of personal growth following a severe sports-related injury: personal strength, improved social life, health benefits, sport benefits, and social support and recognition. The domains of sport-injury related growth identified here are consistent with growth-domains identified in previous personal growth literature. However, they also highlight the importance of contextualizing the experience of growth. We have captured key elements of sport-injury related growth, domains that can be used as the basis for further psychometric testing and for further interventions to increase adjustment and well-being during the rehabilitation process.

Resilience, stress and injuries in the context of the Brazilian elite rhythmic gymnastics.

PLoS One 2018 31;13(12):e0210174. Epub 2018 Dec 31.

Physical Education Department, Universidade Estadual de Maringá, Maringá, Paraná, Brazil.

The study had the goal to study the relationship between resilience, stress and injuries in the sport context. Eight female athletes, part of the Rhythmic Gymnastics Brazilian Team along the Olympic Cycle 2015-2016 participated in the study, with a mean age of 20.4±2.5 years. The following instruments were used: RESTQ-76 Sport, CD-RISC 10, documental analysis of physical therapy records, and structured questionnaire. Data was analyzed by descriptive statistics (frequency, mean and standard deviation); Repeated Measured ANOVA with Bonferroni's post-hoc, Student's "t" test, Friedman test, Pearson Correlation Coefficient, Cohen's d, and inductive thematic analysis. We found relatively stable levels of stress and recovery across the season; total recovery levels were higher than stress at all four measured timepoints (p<0.05); All athletes had at least one injury, with a total of 14 injuries; No significant correlations were found between the quantitative scores of resilience, stress and recovery; Training and the sport's scoring system were the most relevant perceived stressors; athletes presented meta-cognition and a non-positive evaluation (neutral) of stressors; Social support was considered the main psychological factor for the resilience process; such process resulted in improved control and interpretation of emotions; Our hypothesized model proposes that, in the relationship between stress and injuries, resilience acts by optimizing the injury recovery process. It was concluded that resilience plays a role in the process of injury rehabilitation and stress control in elite rhythmic gymnastics' athletes.

A Bayesian Approach to Sport Injuries Likelihood: Does Player's Self-Efficacy and Environmental Factors Plays the Main Role?

Front Psychol 2018 6;9:1174. Epub 2018 Jul 6.

Department of Basic Psychology, University of the Balearic Islands, Palma de Mallorca, Spain.

The psychological factors of sports injuries constitute a growing field of study, even from the point of view of the prediction of their occurrence. Most of them, however, do not take into account the likelihood of the injuries' occurrence and the weight and role of the psychological variables on it. We conducted a study building up a Bayesian Network on a big sample of athletes, trying to assess these probabilistic links among several relevant psychological variables and the injuries' occurrence. The sample was constituted by 297 athletes (239 males, 58 females) from a wide range of sports: track and field; judo; fencing; karate; boxing; swimming; kayaking; artistic rollerskating, and team sports as football, basketball, and handball (Mean age: 25.10 ±-3.87; range: 21-38 years). Several psychological variables, such as anxiety, social support, and self-efficacy were studied. Also, we recorded the history of injuries as well the body mass index and personal epidemiological data. The overall picture of the generated graph and Bayesian Network and its analysis - including the use of hypothetical data by means of several instantiations - includes the nuclear role of the Self-Efficacy regarding the injuries' occurrence likelihood; the decreasing impact of the competitive anxiety previous to the injury; the probabilistic independence of the players' risk behaviors, and the relevance of the environmental clues such the use of coping strategies and social support in order to build up a good level of Self-Efficacy after the occurrence of an injury. All these data are relevant when designing both preventive and recovery interventions from the multidisciplinary as well as from the psychological point of view.

Psychological Profiling of Triathlon and Road Cycling Athletes.

Front Psychol 2018 4;9:825. Epub 2018 Jul 4.

Department of Physical Activity, Universidad de Murcia, Murcia, Spain.

Psychological characteristics of athletes play a key role in sport performance and may moderate and mediate the influence of technical, tactical, and physical abilities athletes show. Different authors have emphasized the special attention such psychological characteristics should receive considering the extent they can influence athletes' behavior either in training or in competition. This paper is aimed at describing the psychological profiles of two cycling sports: triathlon and road cycling. One hundred and twenty-nine male and female professional and amateur cycling athletes (35.74 years old average age ±12.79; 14.94 average number of years practicing cycling ±11.20) were assessed on different psychological characteristics. For that purpose, the Psychological Characteristics related to the Sport Performance (CPRD) Questionnaire and the Psychological Skills Inventory for Sports (PSIS) was used. Results showed significant differences among triathlon and road cyclists (Stress control = =-3.711, = 0.000, = 0.48 ; Influence of Performance Evaluation = =-3-115, = 0.002, = 0.49; Motivation = =-5.520, = 0.000, = 0.82; Mental Skills = =-4.985, = 0.000, = 1.02). There were no significant differences between men and women though there were differences among pros and amateur athletes. Triathlon professional, compared to amateurs, showed higher scores in all the psychological dimensions assessed (Stress control = = 3.005, = 0.003, = 1.07; Influence of Performance Evaluation = = 2.858, = 0.005, 0.77; Motivation = = 2.721, = 0.008, = 0.26; Mental Skills = = 2.556, = 0.012, = 0.77). The results of this descriptive study contribute to establishing a model of optimal psychological profiling applied to the different cycling groups that can be used by sport psychologist, trainers, and coaches in order to promote peak performance of these athletes.

Effectiveness of a stress management pilot program aimed at reducing the incidence of sports injuries in young football (soccer) players.

Phys Ther Sport 2017 Mar 6;24:53-59. Epub 2016 Sep 6.

Department of Basic Psychology, University of Balearic Islands, Crta. Valldemossa, Km 7.5, 07122 Palma, Spain. Electronic address:

Objectives: Several attempts to reduce the incidence of sport injuries using psychosocial interventions produced fruitful, although inconclusive results. This paper presents the effectiveness and implementation issues of a pilot 3-month stress-management and muscle relaxation program aimed at reducing sport injury incidence.

Design: Pre-post treatment-non treatment group comparison.

Program Administration: The program was administered by a trained psychologist on a once-a-week, 1-h session basis.

Participants: Seventy-four male soccer players from four National Youth league teams voluntarily participated. Teams were randomly assigned to either treatment/non-treatment group.

Measures: Injury protocol, Self-monitoring cards, Athletes' satisfaction and commitment survey, Coaches' interview.

Results: Group main effect and Time-Group interaction effect were both statistically significant, F(1,60) = 8.30, p = 0.005, η = 0.121, with the average number of injuries larger in the post-treatment phase of non-treatment group (p = 0.005, η = 0.077). There was a significant decrease in the average number of injuries for the intervention group before and after implementing the program (p < 0.001, η = 0.309).

Conclusions: A controlled implementation of a psychosocial program was effective in reducing youth soccer sport injuries, with a high level of satisfaction and commitment from the athletes, as well as high acceptance from the coaches.

Activation of the cholinergic anti-inflammatory system in peripheral blood mononuclear cells from patients with borderline personality disorder.

J Psychiatr Res 2012 Dec 17;46(12):1610-7. Epub 2012 Oct 17.

Centro de Investigación Biomédica en Red de Salud Mental (CIBERSAM), Spain.

A case-control study including patients (n = 20) with Borderline Personality Disorder (BPD) and healthy controls (n = 33) was carried out. To avoid interferences of other clinical conditions on biological findings, patients were free of current major depressive episodes or substance dependence disorders, and had no life history of schizophrenia, bipolar or neuropsychiatric disorders. Patients were free of medication for at least two weeks at the time of the study. Studies carried out in peripheral mononuclear blood cells and plasma evidence a systemic inflammatory condition in unstable-impulsive BPD patients. Specifically, a significant increase in some intracellular components of two main pro-inflammatory pathways such as iNOS and COX-2, as well as an increase in the plasma levels of the inflammatory cytokine IL1β. Interestingly, patients have an increase in the protein expression of the anti-inflammatory subtype of nicotinic receptor α7nAChR. This finding may reflect a possible mechanism trying to maintain intracellular inflammation pathways under control. All together, these results describe an imbalanced, pro-inflammatory and oxidant phenotype in BPD patients independent of plasma cotinine levels. Although more scientific evidence is needed, the determination of multiple components of pro- and anti-inflammatory cellular pathways have interesting potential as biological markers for BPD and other generalized impulsive syndromes, specially data obtained with α7nAChR and its lack of correlation with plasma levels of nicotine metabolites. Their pharmacological modulation with receptor modulators can be a promising therapeutic target to take into account in mental health conditions associated with inflammatory or oxido/nitrosative consequences. Also, identifying at-risk individuals would be of importance for early detection and intervention in adolescent subjects before they present severe behavioural problems.

Are we more consistent when talking about ourselves than when behaving? Consistency differences through a questionnaire and an objective task.

Span J Psychol 2011 May;14(1):207-17

Departamento de Psicología Biológica y de la Salud, Universidad Autónoma de Madrid, Campus Cantoblanco, 28049 Madrid, Spain.

The present paper aimed to examine questionnaire response patterns and objective task-based test behavioral patterns in order to analyze the differences people show in consistency. It is hypothesized that people tend to be more consistent when talking about themselves (when describing themselves through verbal statements) that when they solve a task (when behaving). Consistency is computed using the pi* statistic (Hernandez, Rubio, Revuelta, & Santacreu, 2006). According to this procedure, consistency is defined as the value and the dimensionality of the latent trait of an individual (theta) remaining invariant through out the test of. Participants who are consistent must show a constant theta and follow a given response pattern during the entire course of the test. A sample of 3,972 participants was used. Results reveal that 68% of participants showed a consistent response pattern when completing the questionnaire. When tackling the task-based test, the percentage was 66%. 45% of individuals showed a consistent pattern in both tests. Implications for personality and individual differences assessment are discussed.

The status of the species Beijerinckia fluminensis Dobereiner and Ruschel 1958. Request for an Opinion.

Int J Syst Evol Microbiol 2011 Jul 22;61(Pt 7):1757-1759. Epub 2011 Apr 22.

Colección Española de Cultivos Tipo (CECT), Parc Científic Universitat de València, 46980 Paterna; and Departamento de Microbiología y Ecología, Universidad de Valencia, 46100 Burjassot, Valencia, Spain.

In a previous article [Oggerin M., Arahal, D. R., Rubio, V. & Marin, I. (2009). Int J Syst Evol Microbiol 59, 2323-2328], it has been shown that strain Beijerinckia fluminensis UQM 1685(T) and its derived equivalent B. fluminensis CIP 106281(T) do not conform to the description of the type strain of Beijerinckia fluminensis Döbereiner and Ruschel 1958. Indeed, both strains were identified as members of the species Rhizobium radiobacter and exhibited marked phenotypic and genotypic differences with members of the genus Beijerinckia. It was concluded that both strains, and any other equivalents derived from them, do not descend from the nomenclatural type. Since then, our attempts to find older deposits of the type strain, hopefully derived from the original isolate, or other existing strains of Beijerinckia fluminensis that could be proposed as a neotype strain, have been in vain. It is therefore proposed that the Judicial Commission should place the name Beijerinckia fluminensis Döbereiner and Ruschel 1958 on the list of rejected names if a suitable replacement type strain or a neotype cannot be found within two years following the publication of this Request (Rule 18c).

Identification of Beijerinckia fluminensis strains CIP 106281T and UQM 1685T as Rhizobium radiobacter strains, and proposal of Beijerinckia doebereinerae sp. nov. to accommodate Beijerinckia fluminensis LMG 2819.

Int J Syst Evol Microbiol 2009 Sep 20;59(Pt 9):2323-8. Epub 2009 Jul 20.

Centro de Biología Molecular Severo Ochoa, Universidad Autónoma de Madrid, Cantoblanco, 28049 Madrid, Spain.

During the course of a research project with free-living, nitrogen-fixing bacteria, we determined the 16S rRNA gene sequence of Beijerinckia fluminensis strains UQM 1685T and CIP 106281T and discovered that they were only 90.6-91.2% similar to the sequences of strains of other Beijerinckia species and subspecies. Moreover, the highest similarity to these sequences (99.7%) corresponded to strains of Rhizobium radiobacter (including Agrobacterium tumefaciens). Other diagnostic features confirmed that the two strains have the same origin but do not descend from the nomenclatural type. At the same time, B. fluminensis LMG 2819 was characterized and it was found that its properties also do not agree with the original description of the species, although it can be considered a member of the genus. Further characterization, including chemotaxonomic and other phenotypic traits, allows us to propose (i) the identification of B. fluminensis strains CIP 106281T and UQM 1685T as strains of Rhizobium radiobacter and (ii) the designation of strain LMG 2819T (=CECT 7311T) as the type strain of a novel species, Beijerinckia doebereinerae sp. nov.

Apoptosis related genes expressed in cultured Fallopian tube epithelial cells infected in vitro with Neisseria gonorrhoeae.

Biol Res 2007 17;40(3):319-27. Epub 2008 Apr 17.

Laboratorio de Inmunología de la Reproducción, Facultad de Química y Biología, Universidad de Santiago de Chile, Santiago, Chile.

Background: Infection of the Fallopian tubes (FT) by Neisseria gonorrhoeae (Ngo) can lead to acute salpingitis, an inflammatory condition resulting in damage primarily to the ciliated cells, with loss of ciliary activity and sloughing of the cells from the epithelium. Recently, we have shown that Ngo infection induced apoptosis in FT epithelium cells by a TNF-alpha dependent mechanism that could contribute to the cell and tissue damage observed in gonococcal salpingitis.

Aim: To investigate the apoptosis-related genes expressed during apoptosis induction in cultured FT epithelial cells infected in vitro by Ngo.

Materials And Methods: In the current study, we used cDNA macroarrays and real time PCR to identify and determine the expression levels of apoptosis related genes during the in vitro gonococci infection of FT epithelial cells.

Results: Significant apoptosis was induced following infection with Ngo. Macroarray analysis identified the expression of multiple genes of the TNF receptor family (TNFRSF1B, -4, -6, -10A, -10B and -10D) and the Bcl-2 family (BAK1, BAX, BLK, HRK and MCL-1) without differences between controls and infected cells. This lack of difference was confirmed by RT-PCR of BAX, Bcl-2, TNFRS1A (TNFR-I) and TNFRSF1B (TNFR-II).

Conclusion: Several genes related to apoptosis are expressed in primary cultures of epithelial cells of the human Fallopian tube. Infection with Ngo induces apoptosis without changes in the pattern of gene expression of several apoptosis-related genes. RESULTS strongly suggest that Ngo regulates apoptosis in the FT by post-transcriptional mechanisms that need to be further addressed.

Influence of impulsivity-reflexivity when testing dynamic spatial ability: sex and g differences.

Span J Psychol 2007 Nov;10(2):294-302

Universidad Complutense de Madrid, Spain.

This work analyzes the possibility that the differences in the performance of men and women in dynamic spatial tasks such as the Spatial Orientation Dynamic Test-Revised (SODT-R; Santacreu & Rubio, 1998), obtained in previous works, are due to cognitive style (Reflexivity-Impulsivity) or to the speed-accuracy tradeoff (SATO) that the participants implement. If these differences are due to cognitive style, they would be independent of intelligence, whereas if they are due to SATO, they may be associated with intelligence. In this work, 1652 participants, 984 men and 668 women, ages between 18 and 55 years, were assessed. In addition to the SODT-R, the "Test de Razonamiento Analitico, Secuencial e Inductivo" (TRASI [Analytical, Sequential, and Inductive Reasoning Test]; Rubio & Santacreu, 2003) was administered as a measure of general intelligence. Impulsivity scores (Zi) of Salkind and Wright (1977) were used to analyze reflexivity-impulsivity and SATO. The results obtained indicate that (a) four performance groups can be identified: Fast-accurate, Slow-inaccurate, Impulsive, and Reflexive. The first two groups solve the task as a function of a competence variable and the last two as a function of a personality variable; (b) performance differences should be attributed to SATO; (c) SATO differs depending on sex and intelligence level.

Sex differences in dynamic spatial ability: the unsolved question of performance factors.

Mem Cognit 2007 Mar;35(2):297-303

Facultad de Psicologia, Universidad Nacional de Educación a Distancia, Madrid, Spain.

Males and females differ in several cognitive abilities, although the largest gap can be found in spatial ability. Some published studies make the claim that performance factors, which can be either subject- or task-related variables, explain these differences. However, previous studies in which performance factors were measured have focused on static spatial tests. Little is known about the role of performance factors in dynamic spatial tasks. In the present study, we analyzed a sample of 2624 university graduates to test the role of three performance factors (response latency, response frequency, and invested time) derived from the Spatial Orientation Dynamic Test-Revised (SODT-R; Santacreu, 1999). The results showed that males and females appear to cope with the dynamic task in different ways. However, males outperformed females even when the effects of the performance factors were partialed out; that is, the assessed performance factors did not explain much of the sex-related variance. Alternative ways of measuring performance factors will be needed if they are to explain sex differences in dynamic spatial ability.

Fluid intelligence, working memory and executive functioning.

Psicothema 2006 Nov;18(4):816-21

Faculty of Psychology, Universidad Autónoma de Madrid, 28049 Madrid, Spain.

The causes underlying the correlation between working memory and fluid intelligence remain unknown. There are some researchers who argue that the answer can be found on the presumed executive component of working memory. However, the available empirical evidence is far from conclusive. The present study tested a sample of 229 participants. Intelligence, working memory, and executive functioning were measured by one analytic reasoning test (TRASI), a dual task combining a primary task of deductive reasoning with a secondary task of counting, and the Tower of Hanoi task, respectively. All the 3 measures were computer administered. The results indicate that the shared variance between executive functioning and working memory do not account for the relationship between intelligence and working memory. Some theoretical implications are discussed.

The order Diatrypales (Ascomycota) contains one single family, the Diatrypaceae. To obtain insight in the phylogenetic relationships within this family, the complete sequences of the ITS region (ITS1, 5.8S rRNA gene and ITS2) of 53 isolates from the five main genera in the family (Diatrype, Diatrypella, Cryptosphaeria, Eutypa and Eutypella) were determined and aligned for phylogenetic reconstruction. Sequence analysis revealed the presence of tandem repeated motifs 11 nucleotides-long, placed in homologous positions along the ITS1 region. Parsimony analysis established the existence of nine monophyletic groups and one branch with a single isolate of Eutypella quaternata. The phylogenetic relationships established by parsimony analysis did not correlate well with classical taxonomic schemes. None of the five genera included in this study was found to be monophyletic. The genera Diatrype, Eutypa and Cryptosphaeria each were divided into two groups. Isolates of Diatrype flavovirens appeared in a clade separated from the one that grouped Diatrype disciformis and the rest of Diatrype species. The Eutypa strains appeared distributed into two clades, one grouping Eutypa lata and related species (Eutypa armeniacae, Eutypa laevata, Eutypa petrakii), and another with the remaining species of the genus. Eutypella (excluding Eutypella quaternaria) appeared as an unstable monophyletic group, which was lost when the sequence alignment was subjected to neighbor-joining analysis. The genus Diatrypella was not associated with any monophyletic group, suggesting that the multisporate asci character has appeared several times during the evolution of the group. Overall, our study suggests the need to revise many of the concepts usually applied to the classification of members of the family.
