Valoración multidisciplinar de las secuelas al mes del alta hospitalaria por neumonía grave COVID-19, ¿existen diferencias en función de la terapia respiratoria empleada durante su ingreso en Cuidados Intensivos? / Multidisciplinary approach of the sequelae one month after hospital discharge in patients with severe bilateral COVID-19 pneumonia, are there differences depending on the respiratory therapy used during admission to intensive care?

Objetivo Describir las secuelas al mes del alta hospitalaria en pacientes que precisaron ingreso en Cuidados Intensivos por neumonía grave COVID-19 y analizar las diferencias entre los que recibieron terapia exclusivamente con oxigenoterapia con alto flujo con respecto a los que precisaron ventilación mecánica invasiva (VMI). Diseño Estudio de cohorte, prospectivo y observacional. Ámbito Consulta multidisciplinar pos Cuidados Intensivos. Pacientes o participantes Pacientes que superaron el ingreso en la Unidad de Cuidados Intensivos (UCI) por neumonía grave COVID-19 desde abril 2020 hasta octubre 2021. Intervenciones Inclusión en el programa multidisciplinar pos UCI. Variables de interés principales Secuelas motoras, sensitivas, psicológicas/psiquiátricas, respiratorias y nutricionales tras el ingreso hospitalario. Resultados Se incluyeron 104 pacientes. 48 pacientes recibieron oxigenoterapia nasal de alto flujo (ONAF) y 56 VMI. Las principales secuelas encontradas fueron la neuropatía distal (33,9% VMI vs. 10,4% ONAF); plexopatía braquial (10,7% VMI vs. 0% ONAF); disminución de fuerza de agarre: mano derecha 20,67 kg (± 8,27) en VMI vs. 31,8 kg (± 11,59) en ONAF y mano izquierda 19,39 kg (± 8,45) en VMI vs. 30,26 kg (± 12,74) en ONAF; y balance muscular limitado en miembros inferiores (28,6% VMI vs. 8,6% ONAF). Las diferencias observadas entre ambos grupos no alcanzaron significación estadística en el estudio multivariable. Conclusiones Los resultados obtenidos tras el estudio multivariable sugieren no existir diferencias en cuanto a las secuelas físicas percibidas al mes del alta hospitalaria en función de la terapia respiratoria empleada, ya fuera ONAF o ventilación mecánica prolongada, si bien son precisos más estudios para poder obtener conclusiones al respecto (AU)

Investigación en nutrición clínica y generación de nuevas evidencias: el programa NutriCOVer / Investigation in clinical nutrition and generation of new evidence: the NutriCOVer program

NutriCOVer es un programa de investigación impulsado por Nutricia a nivel global para apoyar iniciativas de investigación clínica en 16 países de todo el mundo. El programa tiene como objetivo adaptar el cuidado nutricional a las necesidades de los pacientes con COVID-19 dados de alta de la unidad de cuidados intensivos. En España se están desarrollando tres proyectos de investigación, siendo un país de referencia dentro del programa NutriCOVer. Estos estudios analizan la evolución de los pacientes tras una COVID-19 grave desde el punto de vista nutricional, evaluando aspectos relevantes como la prevalencia y evolución de la desnutrición y la sarcopenia (estudio NUTRICOVID), la prevalencia y el impacto de la disfagia (estudio COVID-19-DN-OD) y los cambios de la composición corporal medida por ecografía nutricional y bioimpedanciometría (estudio NUTRIECOMUSCLE). En este artículo, los investigadores que lideran estos tres proyectos discuten todos los pasos que han seguido para el desarrollo de los estudios en el contexto de una pandemia mundial: desde la idea inicial, el diseño y el reclutamiento de pacientes hasta los problemas de ejecución que se han encontrado en el día a día o la política de publicación de los resultados. Además, ofrecen algunas impresiones sobre los resultados iniciales y las implicaciones que pueden tener estos estudios para cambiar la práctica clínica habitual (AU)

NutriCOVer is a global research program sponsored by Nutricia to support initiatives in clinical investigation in 16 countries worldwide. The program's objective is to adapt nutritional care to the needs of patients with COVID-19 who have been discharged from the intensive care unit. In Spain — a reference country for the NutriCOVer program — three research projects are being carried out. These studies analyze the clinical course of COVID-19 patients from a nutritional point of view, evaluating relevant aspects such as the prevalence and evolution of malnutrition and sarcopenia (the NUTRICOVID study), the prevalence and impact of dysphagia (the COVID-19-DN-OD study), or changes in corporal composition measured through nutritional ultrasound and bioimpedance analysis (the NUTRIECOMUSCLE study). In this article, the principal investigators of the three projects discuss the steps taken to develop these studies in the context of a worldwide pandemic: from initial concept, study design, and patient recruitment to problems in the execution of the project in day-to-day practice and publication policies. Also, they offer some insights on the initial results and the implications which these studies may have for current clinical practice (AU)

Chitosan-Calcium-Simvastatin Scaffold as an Inductive Cell-Free Platform.

The development of biomaterials based on the combination of biopolymers with bioactive compounds to develop delivery systems capable of modulating dentin regeneration mediated by resident cells is the goal of current biology-based strategies for regenerative dentistry. In this article, the bioactive potential of a simvastatin (SV)-releasing chitosan-calcium-hydroxide (CH-Ca) scaffold was assessed. After the incorporation of SV into CH-Ca, characterization of the scaffold was performed. Dental pulp cells (DPCs) were seeded onto scaffolds for the assessment of cytocompatibility, and odontoblastic differentiation was evaluated in a microenvironment surrounded by dentin. Thereafter, the cell-free scaffold was adapted to dentin discs positioned in artificial pulp chambers in direct contact with a 3-dimensional (3D) culture of DPCs, and the system was sealed to simulate internal pressure at 20 cm/H2O. In vivo experiments with cell-free scaffolds were performed in rats' calvaria defects. Fourier-transform infrared spectroscopy spectra proved incorporation of Ca and SV into the scaffold structure. Ca and SV were released upon immersion in a neutral environment. Viable DPCs were able to spread and proliferate on the scaffold over 14 d. Odontoblastic differentiation occurred in the DPC/scaffold constructs in contact with dentin, in which SV supplementation promoted odontoblastic marker overexpression and enhanced mineralized matrix deposition. The chemoattractant potential of the CH-Ca scaffold was improved by SV, with numerous viable and dentin sialoprotein-positive cells from the 3D culture being observed on its surface. Cells at 3D culture featured increased gene expression of odontoblastic markers in contact with the SV-enriched CH-Ca scaffold. CH-Ca-SV led to intense mineralization in vivo, presenting mineralization foci inside its structure. In conclusion, the CH-Ca-SV scaffold induces differentiation of DPCs into a highly mineralizing phenotype in the presence of dentin, creating a microenvironment capable of attracting pulp cells to its surface and inducing the overexpression of odontoblastic markers in a cell-homing strategy.

Comorbidity within mental disorders: a comprehensive analysis based on 145 990 survey respondents from 27 countries.

AIMS: Epidemiological studies indicate that individuals with one type of mental disorder have an increased risk of subsequently developing other types of mental disorders. This study aimed to undertake a comprehensive analysis of pair-wise lifetime comorbidity across a range of common mental disorders based on a diverse range of population-based surveys. METHODS: The WHO World Mental Health (WMH) surveys assessed 145 990 adult respondents from 27 countries. Based on retrospectively-reported age-of-onset for 24 DSM-IV mental disorders, associations were examined between all 548 logically possible temporally-ordered disorder pairs. Overall and time-dependent hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox proportional hazards models. Absolute risks were estimated using the product-limit method. Estimates were generated separately for men and women. RESULTS: Each prior lifetime mental disorder was associated with an increased risk of subsequent first onset of each other disorder. The median HR was 12.1 (mean = 14.4; range 5.2-110.8, interquartile range = 6.0-19.4). The HRs were most prominent between closely-related mental disorder types and in the first 1-2 years after the onset of the prior disorder. Although HRs declined with time since prior disorder, significantly elevated risk of subsequent comorbidity persisted for at least 15 years. Appreciable absolute risks of secondary disorders were found over time for many pairs. CONCLUSIONS: Survey data from a range of sites confirms that comorbidity between mental disorders is common. Understanding the risks of temporally secondary disorders may help design practical programs for primary prevention of secondary disorders.

Factors associated with length of stay and readmission in acute psychiatric inpatient services in Portugal.

Assessing the factors that influence duration and number of hospitalizations may support mental health services planning and delivery. This study examines the factors associated with length of stay and readmission in Portuguese psychiatric inpatient services during 2002, 2007 and 2012. Data from all admissions were extracted from clinical files. Logistic regression models estimated the association between length of stay (<17 vs ≥17 days) and number of admissions per year (1 vs >1 admission) with sociodemographic, clinical, and contextual factors. Older age, a diagnosis of psychosis, and compulsory admission were associated with higher odds of longer length of stay. Being married, secondary education, suicide attempt, a diagnosis of substance use and "other mental disorders", being admitted in 2012, and two of the psychiatric inpatient services associated with lower odds of longer length of stay. Being retired (or others), a diagnosis of psychosis, compulsory admission, and psychiatric service were associated with increased odds of readmission. Older age, and secondary and higher education were associated with lower odds of readmission. The findings indicate that multiple factors influence length of stay and readmission. Identifying these factors provides useful evidence for clinicians and policy makers to design more targeted and cost-effective interventions.

Intermittent explosive disorder subtypes in the general population: association with comorbidity, impairment and suicidality.

AIMS: Intermittent explosive disorder (IED) is characterised by impulsive anger attacks that vary greatly across individuals in severity and consequence. Understanding IED subtypes has been limited by lack of large, general population datasets including assessment of IED. Using the 17-country World Mental Health surveys dataset, this study examined whether behavioural subtypes of IED are associated with differing patterns of comorbidity, suicidality and functional impairment. METHODS: IED was assessed using the Composite International Diagnostic Interview in the World Mental Health surveys (n = 45 266). Five behavioural subtypes were created based on type of anger attack. Logistic regression assessed association of these subtypes with lifetime comorbidity, lifetime suicidality and 12-month functional impairment. RESULTS: The lifetime prevalence of IED in all countries was 0.8% (s.e.: 0.0). The two subtypes involving anger attacks that harmed people ('hurt people only' and 'destroy property and hurt people'), collectively comprising 73% of those with IED, were characterised by high rates of externalising comorbid disorders. The remaining three subtypes involving anger attacks that destroyed property only, destroyed property and threatened people, and threatened people only, were characterised by higher rates of internalising than externalising comorbid disorders. Suicidal behaviour did not vary across the five behavioural subtypes but was higher among those with (v. those without) comorbid disorders, and among those who perpetrated more violent assaults. CONCLUSIONS: The most common IED behavioural subtypes in these general population samples are associated with high rates of externalising disorders. This contrasts with the findings from clinical studies of IED, which observe a preponderance of internalising disorder comorbidity. This disparity in findings across population and clinical studies, together with the marked heterogeneity that characterises the diagnostic entity of IED, suggests that it is a disorder that requires much greater research.

Dissolved Carbon Dioxide Sensing Platform for Freshwater and Saline Water Applications: Characterization and Validation in Aquaculture Environments.

A sensing configuration for the real-time monitoring, detection, and quantification of dissolved carbon dioxide (dCO2) was developed for aquaculture and other applications in freshwater and saline water. A chemical sensing membrane, based on a colorimetric indicator, is combined with multimode optical fiber and a dual wavelength light-emitting diode (LED) to measure the dCO2-induced absorbance changes in a self-referenced ratiometric scheme. The detection and processing were achieved with an embeded solution having a mini spectrometer and microcontroller. For optrode calibration, chemical standard solutions using sodium carbonate in acid media were used. Preliminary results in a laboratory environment showed sensitivity for small added amounts of CO2 (0.25 mg·L-1). Accuracy and response time were not affected by the type of solution, while precision was affected by salinity. Calibration in freshwater showed a limit of detection (LOD) and a limit of quantification (LOQ) of 1.23 and 1.87 mg·L-1, respectively. Results in saline water (2.5%) showed a LOD and LOQ of 1.05 and 1.16 mg·L-1, respectively. Generally, performance was improved when moving from fresh to saline water. Studies on the dynamics of dissolved CO2 in a recirculating shallow raceway system (SRS+RAS) prototype showed higher precision than the tested commercial sensor. The new sensor is a compact and robust device, and unlike other sensors used in aquaculture, stirring is not required for correct and fast detection. Tests performed showed that this new sensor has a fast accurate detection as well as a strong potential for assessing dCO2 dynamics in aquaculture applications.

Expression and Immunostaining Analyses Suggest that Pneumocystis Primary Homothallism Involves Trophic Cells Displaying Both Plus and Minus Pheromone Receptors.

The genus Pneumocystis encompasses fungal species that colonize mammals' lungs with host specificity. Should the host immune system weaken, the fungal species can cause severe pneumonia. The life cycle of these pathogens is poorly known, mainly because an in vitro culture method has not been established. Both asexual and sexual cycles would occur. Trophic cells, the predominant forms during infection, could multiply asexually but also enter into a sexual cycle. Comparative genomics revealed a single mating type locus, including plus and minus genes, suggesting that primary homothallism involving self-fertility of each strain is the mode of reproduction of Pneumocystis species. We identified and analyzed the expression of the mam2 and map3 genes encoding the receptors for plus and minus pheromones using reverse transcriptase PCR, in both infected mice and bronchoalveolar lavage fluid samples from patients with Pneumocystis pneumonia. Both receptors were most often concomitantly expressed during infection, revealing that both pheromone-receptor systems are involved in the sexual cycle. The map3 transcripts were subject to alternative splicing. Using immunostaining, we investigated the presence of the pheromone receptors at the surfaces of Pneumocystis cells from a patient. The staining tools were first assessed in Saccharomyces cerevisiae displaying the Pneumocystis receptors at their cellular surface. Both receptors were present at the surfaces of the vast majority of the cells that were likely trophic forms. The receptors might have a role in mate recognition and/or postfertilization events. Their presence at the cell surface might facilitate outbreeding versus inbreeding of self-fertile strains.IMPORTANCE The fungi belonging to the genus Pneumocystis may cause severe pneumonia in immunocompromised humans, a disease that can be fatal if not treated. This disease is nowadays one of the most frequent invasive fungal infections worldwide. Whole-genome sequencing revealed that the sexuality of these fungi involves a single partner that can self-fertilize. Here, we report that two receptors recognizing specifically excreted pheromones are involved in this self-fertility within infected human lungs. Using fluorescent antibodies binding specifically to these receptors, we observed that most often, the fungal cells display both receptors at their surface. These pheromone-receptor systems might play a role in mate recognition and/or postfertilization events. They constitute an integral part of the Pneumocystis obligate sexuality within human lungs, a cycle that is necessary for the dissemination of the fungus to new individuals.

Changes in socioeconomic position among individuals with mental disorders during the economic recession in Portugal: a follow-up of the National Mental Health Survey.

AIMS: Portugal was one of the European countries most affected by the period of economic recession initiated in 2008. Social inequalities are likely to widen during such periods and disproportionately affect people with mental disorders. The present study aims to compare self-reported changes in indicators of socioeconomic position during the economic recession in Portugal among people with and without mental disorders in the beginning of this period. Three dimensions were assessed, namely employment situation, experiences of financial hardship and subjective social status. METHODS: Data from the World Mental Health Survey Initiative Portugal (2008/2009) and from the National Mental Health Survey Follow-up (2015/2016) were used (n = 911). Multinomial and logistic recession models were performed to examine the association between the presence of any 12-month mood or anxiety mental disorder in 2008/2009 and indicators of socioeconomic position in 2015/2016. All analyses were adjusted for gender, age, presence of any physical disorder and education at the baseline. RESULTS: Participants that had any mental disorder in the beginning of the economic recession reported 2.20 (95% CI 1.31-3.71; P < 0.01) higher odds of financial hardship related to daily life in 2015/2016, when compared with those without any mental disorder, after adjusting for age, gender, education and presence of any physical disorder. The results may also suggest a pattern of increased socioeconomic disadvantage among people with prior mental disorder, despite not reaching statistical significance. CONCLUSIONS: The results of this study suggest that the economic recession may have contributed to wider social inequalities between people with and without mental disorders. Policies to support these individuals, such as access to treatment and alleviation of financial hardship, should be a priority in times of economic downturn.

Role of Oral Nutritional Supplements Enriched with ß-Hydroxy-ß-Methylbutyrate in Maintaining Muscle Function and Improving Clinical Outcomes in Various Clinical Settings.

Aging and disease-related malnutrition are well associated with loss of muscle mass and function. Muscle mass loss may lead to increased health complications and associated increase in health care costs, especially in hospitalized individuals. High protein oral nutritional supplements enriched with ß-hydroxy-ß-methylbutyrate (HP-ONS+HMB) have been suggested to provide benefits such as improving body composition, maintaining muscle mass and function and even decreasing mortality rates. The present review aimed to examine current evidence on the effect of HP-ONS+HMB on muscle-related clinical outcomes both in community and peri-hospitalization patients. Overall, current evidence suggests that therapeutic nutrition such as HP-ONS+HMB seems to be a promising tool to mitigate the decline in muscle mass and preserve muscle function, especially during hospital rehabilitation and recovery.

Functional and Expression Analyses of the Pneumocystis MAT Genes Suggest Obligate Sexuality through Primary Homothallism within Host Lungs.

Fungi of the genus Pneumocystis are obligate parasites that colonize mammals' lungs and are host species specific. Pneumocystis jirovecii and Pneumocystis carinii infect, respectively, humans and rats. They can turn into opportunistic pathogens in immunosuppressed hosts, causing severe pneumonia. Their cell cycle is poorly known, mainly because of the absence of an established method of culture in vitro It is thought to include both asexual and sexual phases. Comparative genomic analysis suggested that their mode of sexual reproduction is primary homothallism involving a single mating type (MAT) locus encompassing plus and minus genes (matMc, matMi, and matPi; Almeida et al., mBio 6:e02250-14, 2015). Thus, each strain would be capable of sexual reproduction alone (self-fertility). However, this is a working hypothesis derived from computational analyses that is, in addition, based on the genome sequences of single isolates. Here, we tested this hypothesis in the wet laboratory. The function of the P. jirovecii and P. carinii matMc genes was ascertained by restoration of sporulation in the corresponding mutant of fission yeast. Using PCR, we found the same single MAT locus in all P. jirovecii isolates and showed that all three MAT genes are often concomitantly expressed during pneumonia. Extensive homology searches did not identify other types of MAT transcription factors in the genomes or cis-acting motifs flanking the MAT locus that could have been involved in MAT switching or silencing. Our observations suggest that Pneumocystis sexuality through primary homothallism is obligate within host lungs to complete the cell cycle, i.e., produce asci necessary for airborne transmission to new hosts.IMPORTANCE Fungi of the genus Pneumocystis colonize the lungs of mammals. In immunosuppressed human hosts, Pneumocystis jirovecii may cause severe pneumonia that can be fatal. This disease is one of the most frequent life-threatening invasive fungal infections in humans. The analysis of the genome sequences of these uncultivable pathogens suggested that their sexual reproduction involves a single partner (self-fertilization). Here, we report laboratory experiments that support this hypothesis. The function of the three genes responsible for sexual differentiation was ascertained by the restoration of sexual reproduction in the corresponding mutant of another fungus. As predicted by self-fertilization, all P. jirovecii isolates harbored the same three genes that were often concomitantly expressed within human lungs during infection. Our observations suggest that the sexuality of these pathogens relies on the self-fertility of each isolate and is obligate within host lungs to complete the cell cycle and allow dissemination of the fungus to new hosts.

Complementary and alternative medicine contacts by persons with mental disorders in 25 countries: results from the World Mental Health Surveys.

AIMS: A substantial proportion of persons with mental disorders seek treatment from complementary and alternative medicine (CAM) professionals. However, data on how CAM contacts vary across countries, mental disorders and their severity, and health care settings is largely lacking. The aim was therefore to investigate the prevalence of contacts with CAM providers in a large cross-national sample of persons with 12-month mental disorders. METHODS: In the World Mental Health Surveys, the Composite International Diagnostic Interview was administered to determine the presence of past 12 month mental disorders in 138 801 participants aged 18-100 derived from representative general population samples. Participants were recruited between 2001 and 2012. Rates of self-reported CAM contacts for each of the 28 surveys across 25 countries and 12 mental disorder groups were calculated for all persons with past 12-month mental disorders. Mental disorders were grouped into mood disorders, anxiety disorders or behavioural disorders, and further divided by severity levels. Satisfaction with conventional care was also compared with CAM contact satisfaction. RESULTS: An estimated 3.6% (standard error 0.2%) of persons with a past 12-month mental disorder reported a CAM contact, which was two times higher in high-income countries (4.6%; standard error 0.3%) than in low- and middle-income countries (2.3%; standard error 0.2%). CAM contacts were largely comparable for different disorder types, but particularly high in persons receiving conventional care (8.6-17.8%). CAM contacts increased with increasing mental disorder severity. Among persons receiving specialist mental health care, CAM contacts were reported by 14.0% for severe mood disorders, 16.2% for severe anxiety disorders and 22.5% for severe behavioural disorders. Satisfaction with care was comparable with respect to CAM contacts (78.3%) and conventional care (75.6%) in persons that received both. CONCLUSIONS: CAM contacts are common in persons with severe mental disorders, in high-income countries, and in persons receiving conventional care. Our findings support the notion of CAM as largely complementary but are in contrast to suggestions that this concerns person with only mild, transient complaints. There was no indication that persons were less satisfied by CAM visits than by receiving conventional care. We encourage health care professionals in conventional settings to openly discuss the care patients are receiving, whether conventional or not, and their reasons for doing so.

Fear and distress disorders as predictors of heart disease: A temporal perspective.

OBJECTIVE: Few studies have been able to contrast associations of anxiety and depression with heart disease. These disorders can be grouped in fear and distress disorders. Aim of this study was to study the association between fear and distress disorders with subsequent heart disease, taking into account the temporal order of disorders. METHODS: Twenty household surveys were conducted in 18 countries (n=53791; person years=2,212,430). The Composite International Diagnostic Interview assessed lifetime prevalence and age at onset of disorders, and respondents were categorized into categories based on the presence and timing of fear and distress disorders. Heart disease was indicated by self-report of physician-diagnosed heart disease or self-report of heart attack, together with year of onset. Survival analyses estimated associations between disorder categories and heart disease. RESULTS: Most respondents with fear or distress disorders had either pure distress or pure fear (8.5% and 7.7% of total sample), while fear preceded distress in the large majority of respondents with comorbid fear and distress (3.8% of total sample). Compared to the "no fear or distress disorder" category, respondents with pure fear disorder had the highest odds of subsequent heart disease (OR:1.8; 95%CI:1.5-2.2; p<0.001) and compared to respondents with pure distress disorder, these respondents were at a significantly increased risk of heart disease (OR:1.3; 95%CI:1.0-1.6; p=0.020). CONCLUSION: This novel analytic approach indicates that the risk of subsequent self-reported heart disease associated with pure fear disorder is significantly larger than the risk associated with distress disorder. These results should be confirmed in prospective studies using objective measures of heart disease.

Unemployment, life satisfaction and deprivation: Gender and partnership differences in the context of economic recession.

BACKGROUND: The economic recession produced a rapid rise of unemployment rates that was more visible in Southern European countries. There is evidence that unemployment correlates highly with individuals' poor life satisfaction. OBJECTIVE: To analyse the relationship between life satisfaction, household composition and socioeconomic deprivation in people facing unemployment during the economic recession. METHODS: A sample of 748 unemployed people from Lisbon (Portugal) completed a socio-demographic questionnaire, the Cantril's ladder of life scale, and the latent and manifest benefits of work scale (LAMB). Multiple regression analyses were used to test the associations between life satisfaction and all other variables. RESULTS: Partnered people report higher life satisfaction compared to singles. Financial deprivation and lack of structured time were the strongest factors negatively related to life satisfaction in both partnered and single people. Having children had a particular negative effect on the life satisfaction of partnered men; and living with an unemployed partner together with lack of social contact and high enforced activity had a negative effect on life satisfaction in partnered women. CONCLUSION: The heterogeneity of socioeconomic needs found by household composition bring practical policy implications for support actions targeting unemployed individuals in the unique context of economic recession.

Factors affecting the well-being of adolescents living with unemployed parents in times of economic recession: findings from the Portuguese HBSC study.

OBJECTIVES: Using a national representative sample of adolescents with unemployed parents, this study examined which factors (sociodemographic and of satisfaction with family life and peers) are related to the negative effect of parents' unemployment on emotional well-being. STUDY DESIGN: Cross-sectional survey study. METHODS: Data on adolescents (14.1 ± 1.7 years old), with at least one parent unemployed (n = 1311, 53.2% girls), was provided by the Portuguese Health Behaviour in School-aged Children study. Descriptive statistics and logistic regression analyses were performed. RESULTS: A high proportion of adolescents reported being emotionally affected by father's unemployment but not by their mother's. Older boys and older girls were more likely to report that their same-gender parent's unemployment situation (sons-fathers and daughters-mothers) has had a negative effect on their well-being. Girls from low socio-economic status and with poor family satisfaction were more likely to report negative emotional well-being related to parental unemployment. CONCLUSIONS: This study presents evidence on factors that can shape adolescents' emotional well-being related to parents' unemployment situation. Given the recessionary context and high unemployment rates, these insights are valuable to assist the design of an action to improve the levels of well-being of Portuguese adolescents from unemployed families.

Nanosilicalites as Support for ß-Glucosidases Covalent Immobilization.

Many different materials have been tested for ß-glucosidases immobilization. Such materials, however, often show a poor activity related to a low surface area of the support or even enzyme hindrance caused by entrapment inside porous matrix. In this context, the use of nanosized zeolites as enzymes support is quite new and may be an interesting alternative. The present work evaluates the immobilization of ß-glucosidases in nanosized silicalites by covalent coupling. The new biocatalyst was able to convert 100% of cellobiose into glucose in 18 h at 50 °C and pH 5, retaining 85% of its activity after five cycles of reuse. A detailed investigation of the published literature indicates that, apparently, this is the first work concerning the immobilization of ß-glucosidases on nanosized zeolites ever reported.

Peculiarities of the obese patient with cancer: a national consensus statement by the Spanish Society for the Study of Obesity and the Spanish Society of Medical Oncology.

The relationship between obesity and cancer is clear and is present at all times during course of the disease. The importance of obesity in increasing the risk of developing cancer is well known, and some of the most prevalent tumours (breast, colorectal, and prostate) are directly related to this risk increase. However, there is less information available on the role that obesity plays when the patient has already been diagnosed with cancer. Certain data demonstrate that in some types of cancer, obese patients tolerate the treatments more poorly. Obesity is also known to have an impact on the prognosis, favouring lower survival rates or the appearance of secondary tumours. In this consensus statement, we will analyse the scientific evidence on the role that obesity plays in patients already diagnosed with cancer, and the available data on how obesity control can improve the quality of daily life for the cancer patient.
