RESUMEN

Fungi are incredibly diverse, but they are unexplored, especially in the subalpine and alpine zone. Mortierellaceae are certainly one of the most abundant, species-rich, and widely distributed cultivable soil fungal families in terrestrial habitats, including subalpine and alpine zones. The phylogeny of Mortierellaceae was recently resolved based on current state of the art molecular techniques, and the paraphyletic genus Mortierella sensu lato (s.l.) was divided into 13 monophyletic genera. Our extensive sampling campaigns in the Austrian Alps resulted in 139 different Mortierellaceae pure culture isolates representing 13 new species. For the definition of taxa, we applied both classical morphological criteria, as well as modern DNA-based methods. Phylogenetic relationships were resolved based on the ribosomal DNA internal transcribed spacer (rDNA ITS), the large subunit (LSU), and the DNA-directed RNA polymerase II largest subunit 1 (RPB1). In this study, we proposed a new genus and described 13 new species belonging to the genera Entomortierella, Linnemannia, Mortierella and Podila. In addition, we proposed eight new combinations, re-defined E. jenkinii at species level, defined a neotype for M. alpina and lecto- as well as epitypes for M. fatshederae, M. jenkinii, and M. longigemmata. The rDNA ITS region is generally applied as classical barcoding gene for fungi. However, the obtained phylogenetic resolution is often too low for an accurate identification of closely related species of Mortierellaceae, especially for small sampling sizes. In such cases, unambiguous identification can be obtained based on morphological characters of pure culture isolates. Therefore, we also provide dichotomous keys for species identification within phylogenetic lineages.

RESUMEN

Introduction: The purpose of this mixed-methods study was to evaluate an interprofessional academic-practice partnership in end of life care by examining patient medication outcomes, the contributions of student pharmacists and a pharmacy preceptor to care teams, and student learning experiences. Methods: Retrospective chart review assessed polypharmacy differences in hospice patients with a primary terminal diagnosis of non-Alzheimer's dementia between two patient groups; Group 1 managed on interprofessional care teams within the pharmacy partnership, and Group 2, managed on teams without a pharmacist. Team members who interacted with student pharmacists and the pharmacy preceptor participated in semi-structured key informant interviews to document perceptions of pharmacy contributions to care teams and the organization. At the end of their APPE, students completed reflective writings regarding their learning. Results: Patients in Group 1 were on statistically significant fewer medications than Group 2 at both week 4 and weeks 7-12 following admission. Five conceptual themes emerged from interviews: pharmacists as team medication experts, improved patient outcomes, interprofessional collaboration, patient/caregiver trust in medication regimens, and desire for sustainability. Student reflections included the following learning themes: teamwork, respect, value, and patient-centered care. Conclusions: The addition of a pharmacist on interprofessional care teams decreased the average number of medications in the non-Alzheimer's end of life patient population. Team members identified value-added contributions of student pharmacists and the pharmacy preceptor that enhanced team efficiency and patient care. Student pharmacists recognized these contributions and the experience served as an exemplar of interprofessional practice.

RESUMEN

We present novel experimental results of negative ion formation of halothane (C2HBrClF3) upon electron transfer from hyperthermal neutral potassium atoms (K°) in the collision energy range of 8-1000 eV. The experiments were performed in a crossed molecular beam setup allowing a comprehensive analysis of the time-of-flight (TOF) mass negative ions fragmentation pattern and a detailed knowledge of the collision dynamics in the energy range investigated. Such TOF mass spectra data show that the only negative ions formed are Br-, Cl- and F-, with a strong energy dependence in the low-energy collision region, with the bromine anion being the most abundant and sole fragment at the lowest collision energy probed. In addition, potassium cation (K+) energy loss spectra in the forward scattering direction were obtained in a hemispherical energy analyser at different K° impact energies. In order to support our experimental findings, ab initio quantum chemical calculations have been performed to help interpret the role of the electronic structure of halothane. Potential energy curves were obtained along the C-X (X = Br, Cl) coordinate to lend support to the dissociation processes yielding anion formation.

RESUMEN

INTRODUCTION: The aim of our article is to present the results and experience with the method E.P.Si.T. - endoscopic pilonidal sinus treatment. METHODS: The operation is performed using a special endoscope - fistuloscope. In the first phase, we determine the extent and look for all the sinus tracts. In the second phase, the whole complex  is treated with a grasper, a brush and an electrode from the inside. RESULTS: A total of 21 operations were performed at our department from December 2018 through September 2019. In our sample, men predominated  6:1. Mean age of the patients was 27 years. Complete healing was achieved in 18 patients. Two patients were not healed primarily. One patient was lost to follow-up. CONCLUSION: According to the first experience and results, the E.P.Si.T. seems to be a very good method for treating pilonidal sinus. Compared to open procedures, the length of hospitalization, the need for analgesics and antibiotics were significantly reduced. The period of convalescence was shortened and the return to normal life was faster. The size of the cohort and the duration of post-operative follow-up do not allow us yet to statistically evaluate the results.

RESUMEN

We have performed comprehensive charge-transfer experiments yielding negative ion formation in collisions of fast neutral potassium atoms with nitroimidazole and methylated derivative molecules. The anionic pattern reveals that in the unimolecular decomposition of the precursor parent anion, single and multiple bond cleavages are attained. Selective excision of hydrogen atoms from the N1 position in 4-nitroimidazole (4NI) is completely blocked upon methylation in 1-methyl-4-nitroimidazole (1m4NI) and 1-methyl-5-nitroimidazole (1m5NI). Additionally, only 4NI and 2-nitroimidazole (2NI) are efficient in selectively producing neutral •OH and NO• radicals in contrast to 1m4NI and 1m5NI. These findings present a novel experimental evidence of selective chemical bond breaking by just tuning the proper collision energy in atom-molecule collision experiments. The present work contributes to the current need of pinpointing a class of charge-transfer collisions that exhibit selective reactivity of the kind demonstrated here, extending to tailored chemical control for different applications such as tumor radiation therapy through nitroimidazole-based radiosensitization.

RESUMEN

Fabry disease is an X-linked lysosomal storage disorder caused by mutations in the GLA gene coding for α-galactosidase A (α-GalA). The deleterious mutations lead to accumulation of α-GalA substrates, including globotriaosylceramide (Gb3) and globotriaosylsphingosine. Progressive glycolipid storage results in cellular dysfunction, leading to organ damage and clinical disease, i.e. neuropathic pain, impaired renal function and cardiomyopathy. Many Fabry patients are treated by bi-weekly intravenous infusions of replacement enzyme. While the only available oral therapy is an α-GalA chaperone, which is indicated for a limited number of patients with specific 'amenable' mutations. Lucerastat is an orally bioavailable inhibitor of glucosylceramide synthase (GCS) that is in late stage clinical development for Fabry disease. Here we investigated the ability of lucerastat to lower Gb3, globotriaosylsphingosine and lysosomal staining in cultured fibroblasts from 15 different Fabry patients. Patients' cells included 13 different pathogenic variants, with 13 cell lines harboring GLA mutations associated with the classic disease phenotype. Lucerastat dose dependently reduced Gb3 in all cell lines. For 13 cell lines the Gb3 data could be fit to an IC50 curve, giving a median IC50 [interquartile range (IQR)] = 11 µM (8.2-18); the median percent reduction (IQR) in Gb3 was 77% (70-83). Lucerastat treatment also dose dependently reduced LysoTracker Red staining of acidic compartments. Lucerastat's effects in the cell lines were compared to those with current treatments-agalsidase alfa and migalastat. Consequently, the GCS inhibitor lucerastat provides a viable mechanism to reduce Gb3 accumulation and lysosome volume, suitable for all Fabry patients regardless of genotype.

RESUMEN

OBJECTIVES: Despite promising research showing that physical activity (PA) might improve cognitive functioning in people with mild cognitive impairment (MCI), people with MCI are less physically active compared with the general population. Therefore, the aim of this study was to assess PA correlates among community-dwelling older people with MCI in six low- and middle-income countries. DESIGN: Cross-sectional data from the World Health Organization's Study on Global Ageing and Adult Health were analysed. METHODS: PA level was assessed by the Global Physical Activity Questionnaire. 4854 participants with MCI (mean age 64.4 years; 55.1% females) were grouped into those who do and do not (low PA) meet the 150 min of moderate-to-vigorous PA per week recommendation. Associations between PA and the correlates were examined using multivariable logistic regressions. RESULTS: The prevalence of low PA was 27.4% (95% confidence interval = 25.0-30.0). In the multivariable analysis, older age and unemployment were the only sociodemographic correlates of low PA. The significant positive correlates of low PA in other domains included depression, being underweight, obesity, asthma, chronic lung disease, hearing problems, visual impairment, slow gait, weak grip strength, poor self-rated health, and lower levels of social cohesion. CONCLUSIONS: The current data illustrate that a number of sociodemographic and health factors are associated with PA levels among older people with MCI. The promotion of social cohesion may increase the efficacy of public health initiatives while from a health care perspective, somatic co-morbidities, muscle strength and slow gait need to be considered when activating those at risk for dementia.

RESUMEN

BACKGROUND: Omalizumab is approved as add-on therapy for the treatment of severe uncontrolled allergic asthma. Increase in quality of life and decrease of exacerbations and hospital admission, as well as immunmodulatory effects have been described with omalizumab therapy. However, to date there are few parameters to monitor success and to evaluate the individual advantage of this therapy for the patient. Furthermore, no reliable parameter to predict response to treatment exists so far. The aim of this study was to define an easily applicable parameter for response to treatment with omalizumab. METHOD: 43 patients with allergic asthma were treated with omalizumab at a dose of at least 0,016 mg/kg/IgE every 4 weeks. Before, and 12 weeks after initiation of therapy, bodyplethysmography including airway resistance was performed. Efficacy of treatment was judged by the attending physician on the basis of a five point chart. Furthermore, a differential blood count was performed before, and 12 weeks after initiation of treatment. Total and specific IgE against all relevant antigens were determined before start of therapy. RESULTS: Airway resistance in patients with response to treatment with omalizumab (responders) was significantly decreased in comparison to patients without clinical benefit (non-responder). The number of eosinophil granulocytes in the peripheral blood was decreased in both groups without significant difference. Response to therapy was associated with younger age and lower levels of specific IgE against the allergen with the highest sIgE-level (seasonal and perennial), but not with the sIgE level of the perennial allergens in general. CONCLUSION: Measurement of airway resistance might be an additional parameter for monitoring response to therapy with omalizumab. High specific IgE levels, for both perennial and concomitant seasonal allergens as well as increasing age, seem to predict less favorable treatment outcomes.

RESUMEN

Physical activity (PA) interventions have been shown to improve the health of people living with HIV (PLWH), yet treatment dropout poses an important challenge. We conducted a meta-analysis to investigate the prevalence and predictors of treatment dropout in PA interventions in PLWH. Electronic databases were searched for records up to September 2016. Randomized control trials of PA interventions in PLWH reporting dropout rates were included. Random effects meta-analysis and meta-regression analyses were employed. In 36 studies involving 49 PA intervention arms, 1128 PLWH were included (mean age = 41.6 years; 79.3% male; 39% White). The trim and fill adjusted treatment dropout rate was 29.3% (95% CI = 24.5-34.7%). There was a significant lower dropout rate in resistance training interventions compared with aerobic (p = 0.003) PA interventions, in studies utilizing supervised interventions throughout the study period (p < 0.001), and in studies using adequately qualified professionals (p < 0.001). Exerciser/participant variables that moderated higher dropout rates were a lower percentage of male participants (ß = 1.15, standard error (SE) = 0.49, z = 2.0, p = 0.048), a lower body mass index(BMI) (ß = 0.14, SE = 0.06, z = 2.16, p = 0.03), and a lower cardiorespiratory fitness (ß = 0.10, SE = 0.04, z = 2.7, p = 0.006). The dropout from PA interventions is much higher in PLWH than in many other populations with chronic morbidities. Qualified professionals (i.e., exercise physiologists, physical educators, or physical therapists) should be incorporated as key care providers in the multidisciplinary care of HIV/AIDS and should prescribe supervised PA for PLWH in order to enhance adherence and reduce the burden of HIV/AIDS. Special attention should be given men, those with a higher BMI, and those with a lower cardiorespiratory fitness.

RESUMEN

OBJECTIVE: Cardiorespiratory fitness (CRF) is a major modifiable risk factor for cardiovascular disease (CVD). We conducted a clinical overview to highlight the reduced CRF expressed as maximal oxygen uptake (VO2max) (or predicted) or peak oxygen uptake (VO2 peak) in people with schizophrenia compared to the general population. We also aimed to identify correlates of and clinical strategies to improve CRF. METHOD: We systematically searched major electronic databases from inception until November 2014. A meta-analysis calculating the standardised mean difference (SMD) was employed. RESULTS: CRF was significantly reduced in people with schizophrenia (n = 154) with a SMD of -0.96 (95% CI -1.29 to -0.64) (N = 5) compared to controls (n = 182). Negative symptoms, increased body mass index and female gender were negatively associated with CRF. Promoting physical activity may improve CRF in people with schizophrenia by up to 4-4.5 ml/kg/min following a 6-8 weeks programme (N = 4, n = 98). CONCLUSION: People with schizophrenia have a large and significantly reduced CRF. Given the overwhelming evidence for physical activity as the cornerstone of preventing and managing CVD in the general population, incorporating such interventions in the treatment of people with schizophrenia is justified and urgently required. We present clear practical strategies of how this can be achieved within clinical settings.

RESUMEN

In contrast to odontogenic cysts, keratocystic odontogenic tumours often recur and require more aggressive surgical treatment, so we tried to find features that distinguished between them on magnetic resonance imaging (MRI). Without knowing the diagnosis, two radiologists reviewed intensity (low, intermediate, or high) and homogeneity (homogeneous or heterogeneous) of signals in short-tau-inversion-recovery (STIR), T1- and T2-weighted, and fat-suppressed, contrast-enhanced MRI in 20 consecutive patients with oval, radiolucent lesions of the mandible on panoramic radiography, and who were subsequently confirmed histopathologically to have either an odontogenic cyst or a keratocystic odontogenic tumour (n=10 in each group). Fisher's exact test was statistically significant at p<0.05. Delineation of a contrast-enhanced wall of a cyst with high signal intensity distinguished odontogenic cysts (9/10 and 8/10, respectively) from keratocystic odontogenic tumours (3/10, p=0.02, and 1/10, p=0.01, respectively). One radiologist found odontogenic cysts were more likely to be homogeneous on unenhanced T1-weighted images (odontogenic cysts 9/10, keratocystic odontogenic tumours 3/10, p=0.02) and one on contrast-enhanced MRI, when the cyst wall was enhanced (odontogenic cysts 7/9, keratocystic odontogenic tumours 0/3, p=0.01). There were no other significant distinguishing features on MRI. In conclusion, the signal intensity of the enhanced wall seems to be a feature on contrast-enhanced MRI that differentiates odontogenic cysts from keratocystic odontogenic tumours.

RESUMEN

This feasibility study investigated a two-step biorefining approach to increase the value gained by recycling of organic municipal solid waste. Firstly, lactic acid was produced via batch fermentation at 37°C using the indigenous microbiome. Experiments revealed an optimal fermentation period of 24h resulting in high yields of lactic acid (up to 37gkg(-1)). The lactic acid proportion of total volatile fatty acid content reached up to 83%. Lactobacilli were selectively enriched to up to 75% of the bacterial community. Additionally conversion of organic matter to lactic acid was increased from 22% to 30% through counteracting end product inhibition by continuous lactic acid extraction. Secondly, fermentation residues were used as co-substrate in biomethane production yielding up to 618±41Nmlbiomethaneg(-1) volatile solids. Digestate, the only end product of this process can be used as organic fertilizer.

RESUMEN

OBJECTIVES: The aim of this study was to evaluate the efficacy of a repeated single-dose rituximab (RTX) regimen for remission induction and maintenance in anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). METHOD: We performed a retrospective analysis of all patients with an established diagnosis of AAV who were treated with single-dose RTX infusions at our institution. Clinical outcome data were assessed over a period of 24 months. RESULTS: Sixteen patients were treated for remission induction and maintenance and one patient was treated for only maintenance therapy. Remission (absence of disease activity during the past 3 months and a prednisolone dose of ≤ 7.5 mg) was achieved in 11 patients (68%) with a mean time to remission of 9.4 (range 3-24) months. At 6 months, six patients (37.5%) were in remission and the mean prednisolone dose of all responding patients was 8.2 mg. Five patients had treatment failure due to early relapsing (n = 4) or persistently active (n = 1) disease. At 24 months, nine of the 11 responding patients (82%) were in remission. All patients still had concomitant steroid and/or disease-modifying anti-rheumatic drug (DMARD) therapy at 24 months. Overall, 11 relapses were seen in nine patients (five non-responders and four responders) with a mean time to relapse of 5.3 (range 4-24) months. No major relapses were observed in the responding patients. Severe infections were only seen in patients who had been previously treated with cyclophosphamide (CYC). CONCLUSIONS: The combination of single-dose RTX with other immunosuppressants seems less effective than the standard RTX regimen for the induction of remission of AAV.

RESUMEN

BACKGROUND: Individuals with depression have an elevated risk of cardiovascular disease (CVD) and metabolic syndrome (MetS) is an important risk factor for CVD. We aimed to clarify the prevalence and correlates of MetS in persons with robustly defined major depressive disorder (MDD). METHOD: We searched Medline, PsycINFO, EMBASE and CINAHL up until June 2013 for studies reporting MetS prevalences in individuals with MDD. Medical subject headings 'metabolic' OR 'diabetes' or 'cardiovascular' or 'blood pressure' or 'glucose' or 'lipid' AND 'depression' OR 'depressive' were used in the title, abstract or index term fields. Manual searches were conducted using reference lists from identified articles. RESULTS: The initial electronic database search resulted in 91 valid hits. From candidate publications following exclusions, our search generated 18 studies with interview-defined depression (n = 5531, 38.9% male, mean age = 45.5 years). The overall proportion with MetS was 30.5% [95% confidence interval (CI) 26.3-35.1] using any standardized MetS criteria. Compared with age- and gender-matched control groups, individuals with MDD had a higher MetS prevalence [odds ratio (OR) 1.54, 95% CI 1.21-1.97, p = 0.001]. They also had a higher risk for hyperglycemia (OR 1.33, 95% CI 1.03-1.73, p = 0.03) and hypertriglyceridemia (OR 1.17, 95% CI 1.04-1.30, p = 0.008). Antipsychotic use (p < 0.05) significantly explained higher MetS prevalence estimates in MDD. Differences in MetS prevalences were not moderated by age, gender, geographical area, smoking, antidepressant use, presence of psychiatric co-morbidity, and median year of data collection. CONCLUSIONS: The present findings strongly indicate that persons with MDD are a high-risk group for MetS and related cardiovascular morbidity and mortality. MetS risk may be highest in those prescribed antipsychotics.

RESUMEN

Helium droplets are doped with fullerenes (either C60 or C70) and hydrogen (H2 or D2) and investigated by high-resolution mass spectrometry. In addition to pure helium and hydrogen cluster ions, hydrogen-fullerene complexes are observed upon electron ionization. The composition of the main ion series is (H2)(n)HC(m)(+) where m = 60 or 70. Another series of even-numbered ions, (H2)(n)C(m)(+), is slightly weaker in stark contrast to pure hydrogen cluster ions for which the even-numbered series (H2)(n)(+) is barely detectable. The ion series (H2)(n)HC(m)(+) and (H2)(n)C(m)(+) exhibit abrupt drops in ion abundance at n = 32 for C60 and 37 for C70, indicating formation of an energetically favorable commensurate phase, with each face of the fullerene ion being covered by one adsorbate molecule. However, the first solvation layer is not complete until a total of 49 H2 are adsorbed on C60(+); the corresponding value for C70(+) is 51. Surprisingly, these values do not exhibit a hydrogen-deuterium isotope effect even though the isotope effect for H2/D2 adsorbates on graphite exceeds 6%. We also observe doubly charged fullerene-deuterium clusters; they, too, exhibit abrupt drops in ion abundance at n = 32 and 37 for C60 and C70, respectively. The findings imply that the charge is localized on the fullerene, stabilizing the system against charge separation. Density functional calculations for C60-hydrogen complexes with up to five hydrogen atoms provide insight into the experimental findings and the structure of the ions. The binding energy of physisorbed H2 is 57 meV for H2C60(+) and (H2)2C60(+), and slightly above 70 meV for H2HC60(+) and (H2)2HC60(+). The lone hydrogen in the odd-numbered complexes is covalently bound atop a carbon atom but a large barrier of 1.69 eV impedes chemisorption of the H2 molecules. Calculations for neutral and doubly charged complexes are presented as well.

RESUMEN

Multiple attachment of CO2 to the monomer, dimer and trimer cations of C60 has been observed in the mass spectra of He nanodroplets sequentially doped with C60 and CO2 and exposed to electron ionization at 50 eV. Remarkable anomalies were seen in the ion yield for CO2 coverage for (C60)2+(CO2)8 and (C60)3+(CO2)1,2. These provide insight into the influence of steric properties on the nature of physisorption. The enhanced stabilities of (C60)2+(CO2)8 and (C60)3+(CO2)1,2 are attributed to physisorption inside the "groove" of the dimer and the two "dimples" in the trimer cations of C60. Molecular dynamics simulations provide a qualitative assessment of the observed physisorption and a useful visualization of structural aspects.

RESUMEN

BACKGROUND: More than three out of four persons with binge eating disorder do not get enough physical exercise. AIM: To collect scientific evidence of the effects and benefits that movement and physical exercise can have on persons with a binge eating disorder. METHOD: PubMed, PsychInfo, Cumulative Index to Nursing and Allied Health Literature, Cochrane Library, Physiotherapy Evidence Database, the Dutch Journal of Psychiatry (Tijdschrift voor Psychiatrie), het Tijdschrift voor Vaktherapie and Actual Themata derived from psychomotor therapy were screened for the period January 1994 to August 2011. The methodological quality of the studies was determined on the basis of a checklist. Evidence for the effectiveness of the interventions was summarised by best-evidence synthesis. RESULTS: Eight studies met the inclusion and exclusion criteria. Strong evidence was found for: 1) significant weight-loss after movement interventions; 2) fewer symptoms of depression after a combination of both movement and cognitive behavioural therapy (CBT) than after CBT on its own. There was only limited evidence for 1) the fact that the combination of movement and CBT leads to less eating disorder pathology than does CBT alone; 2) the beneficial effects of yoga on weight-loss as well as on the reduction of eating disorder pathology.There are indications that walking can be helpful in reducing of eating disorder pathology. CONCLUSIONS: Activities involving movement and physical exercise deserve to play an important role in the multidisciplinary treatment of binge eating disorders.

RESUMEN

OBJECTIVE: The objective of this systematic review was to assess the effectiveness of yoga as a complementary treatment on general psychopathology, positive and negative symptoms and health-related quality of life (HRQL) for people with schizophrenia. METHOD: Randomised controlled trials (RCTs) were considered whether they investigated a yoga intervention in patients with schizophrenia. The selection of studies, data extraction and quality assessment were performed independently by two reviewers. RESULTS: Only three RCTs met the inclusion criteria. Lower Positive and Negative Syndrome Scale (PANSS) total scores and subscale scores for positive and negative symptoms were obtained after yoga compared with exercise or waiting list control conditions. In the same way, the physical, psychological, social and environmental HRQL as measured with the abbreviated version of the World Health Organization Quality of Life questionnaire (WHOQOL-BREF) increased more significantly after yoga than after exercise or waiting list control conditions. None of the RCTS encountered adverse events. Dose-response relationships could, however, not be determined. CONCLUSION: Although the number of RCTs included in this review was limited, results indicated that yoga therapy can be an useful add-on treatment to reduce general psychopathology and positive and negative symptoms. In the same way, HRQL improved in those antipsychotic-stabilised patients with schizophrenia following yoga.

RESUMEN

OBJECTIVE: The 6-minute walk test (6MWT) is commonly used to measure the functional exercise capacity in chronic patients with cardiovascular diseases. The purpose of this study was to determine whether the 6MWT is associated with the global assessment of functioning (GAF) score in patients with schizophrenia. METHODS: A total of 68 male and 25 female in-patients with schizophrenia (34.6 ± 9.7 years; body mass index = 24.9 ± 4.4) performed a 6MWT and were assessed with the GAF scale and the Psychosis Evaluation tool for Common use by Caregivers (PECC). RESULTS: The mean distance walked on the 6MWT was 587.3 ± 98.4 m, while the mean GAF score was 52.0 ± 10.4. The Pearson's correlation coefficient between the 6MWT and the GAF score was 0.59 (P < 0.001), indicating a moderate association between both measures. The 6MWT was also significantly related to negative (r = -0.45, P < 0.001), depressive (r = -0.48, P < 0.001) and cognitive (r=, P) symptoms and with body mass index (r = -0.31, P < 0.005), smoking behaviour (r = -0.36, P < 0.001)) and dose of antipsychotic medication (r = -0.38, P < 0.001). CONCLUSION: Next to the GAF scale, clinicians in in-patient settings should consider incorporating the 6MWT into their test battery to measure the functional consequences of schizophrenia and its treatment.

RESUMEN

OBJECTIVE: To investigate the reproducibility of the Eurofit physical fitness test battery in patients with schizophrenia or schizoaffective disorder. Secondary aims were to assess clinical and demographic characteristics that correlate with the performance on the Eurofit and evaluation of the feasibility of the test. METHODS: Fifty patients with schizophrenia or schizoaffective disorder (mean age of 32.9±9.5 years) with a mean body mass index (BMI) of 26.1±6.0 kg/m(2) performed two Eurofit tests administered within 3 days. RESULTS: All Eurofit items showed good reproducibility with intraclass correlation coefficients ranging from 0.72 for flamingo balance to 0.98 for standing broad jump test. All participants could perform five of the seven test items without problems. The whole body balance and abdominal muscle endurance test could be executed by 74 and 90%, respectively. Significant correlations were found with age, BMI, waist circumference, dose of antipsychotic medication and extrapyramidal, negative and cognitive symptoms. CONCLUSIONS: The Eurofit test showed good reproducibility and can be recommended for evaluating physical fitness parameters in patients with schizophrenia or schizoaffective disorder. Physical fitness measures were related to both physical and mental health parameters.
