RESUMO

Hemp seeds are currently used mainly for oil extraction, generating waste that could be potentially exploited further as a source of proteins and other bioactives. This study aims to valorise hemp waste (Cannabis sativa, L.) from previous oil extraction as a source of protein by analysing the effect of high-pressure processing (HPP) pre-treatments (0-600 MPa; 4-8 min) combined with conventional or ultrasound-assisted extraction (UAE) methods on protein recovery/purity, amino acid composition, and protein structure. Overall, maximum protein recovery (≈62%) was achieved with HPP (200 MPa, 8 min) with UAE. The highest protein purity (≈76%) was achieved with HPP (200 MPa, 4 min) with UAE. Overall, UAE improved the extraction of all amino acids compared to conventional extraction independently of HPP pre-treatments. Arg/Lys ratios of the protein isolates ranged between 3.78 and 5.34, higher than other vegetable protein sources. SDS-PAGE did not show visible differences amongst the protein isolates. These results seem to indicate the advantages of the use of UAE for protein recovery in the food industry and the need for further studies to optimise HPP/UAE for an accurate estimation of processing costs and their effects on the composition and structure of proteins to contribute further to the circular economy.

RESUMO

Meningioma-1 is a transcription activator that regulates mammalian palate development and is required for appropriate osteoblast proliferation, motility, differentiation, and function. Microdeletions involving the MN1 gene have been linked to syndromes including craniofacial anomalies, such as Toriello-Carey syndrome. Recently, truncating variants in the C-terminal portion of the MN1 transcriptional factor have been linked to a characteristic and distinct phenotype presenting with craniofacial anomalies and partial rhombencephalosynapsis, a rare brain malformation characterized by midline fusion of the cerebellar hemispheres with partial or complete loss of the cerebellar vermis. It has been called MN1 C-terminal truncation (MCTT) syndrome or CEBALID (Craniofacial defects, dysmorphic Ears, Brain Abnormalities, Language delay, and Intellectual Disability) and suggested to be caused by dominantly acting truncated protein MN1 instead of haploinsufficiency. As a proto-oncogene, MN1 is also involved in familial meningioma. In this study, we present a novel case of MCTT syndrome in a female patient presenting with craniofacial anomalies and rhombencephalosynapsis, harboring a de novo pathogenic variant in the MN1 gene: c.3686_3698del, p.(Met1229Argfs*87).

RESUMO

Mechanical thrombectomy (MT) in pediatric stroke is supported by studies in adults, but there is controversy regarding younger patients. The main growth of intracranial vessels occurs up to 2 years when there can be more difficulties in MT.Description of the MT performed in a 2-month-old patient-the youngest infant published to date. We also review the literature on MT for stroke in infants.A 2-month-old patient presented with an awakening stroke secondary to an occlusion of the M1 segment of the left middle cerebral artery. A successful MT was performed with an aspiration device without clinically significant complications. An etiological study was completed, and neuroimaging showed focal cerebral arteriopathy. The 3-month outcome was excellent: the pediatric modified Rankin score was 0.Including this case, MT for acute stroke has been reported in only 10 infants. MT was successful in 90%, mostly using adult conventional stent retrievers. There were complications only in patients with mechanical circulatory support (MCS) devices; three patients died due to hemorrhagic transformation after MT and one patient died due to recurrent ischemic stroke.MT seems effective and safe in infants similarly to other pediatric ages. In children under 2 years of age, the presence of comorbidities requiring MCS devices is the main factor underlying poor prognosis.

RESUMO

In recent decades, efforts have been made to achieve a positive coexistence among adolescents in secondary schools and create a healthy environment to prepare them to face the present-day challenges. Therefore, this study highlights the educational purpose of improving emotional management and social skills as well as decreasing antisocial and criminal behaviour among secondary education students through an educational training programme. Accordingly, to verify the effectiveness of the project, a quasi-experimental design with a pre-test/post-test structure and a control group was adopted. To achieve this, a total of 141 Spanish secondary school students participated in this study and were randomly assigned to one of two experimental conditions. The first (experimental) group (n = 55) participated in the training programme; correspondingly, the second group (control) (n = 57) followed the usual mentoring activities planned for the entire educational centre. Of the total number of participants, 52.7% of the sample were men and 47.3% were women. The mean age of the participants was 13.01 years old (SD = 0.935). The results showed improvements in the environment with adequate training and the correct application of a programme involving emotional intelligence (EI) among secondary education students. Furthermore, a decrease in conflicts and enhanced relations between the members of the educational community was evidenced. Finally, the practical implications for improving coexistence in secondary schools are discussed.

RESUMO

BACKGROUND: Bacterial colonisation in chronic obstructive pulmonary disease (COPD) contributes to airway inflammation and modulates exacerbations. We assessed risk factors for bacterial colonisation in COPD. METHODS: Patients with stable COPD consecutively recruited over 1 year gave consent to provide a sputum sample for microbiologic analysis. Bronchial colonisation by potentially pathogenic microorganisms (PPMs) was defined as the isolation of PPMs at concentrations of > or =102 colony-forming units (CFU)/mL on quantitative bacterial culture. Colonised patients were divided into high (>105 CFU/mL) or low (<105 CFU/mL) bacterial load. RESULTS: A total of 119 patients (92.5% men, mean age 68 years, mean forced expiratory volume in one second [FEV1] [% predicted] 46.4%) were evaluated. Bacterial colonisation was demonstrated in 58 (48.7%) patients. Patients with and without bacterial colonisation showed significant differences in smoking history, cough, dyspnoea, COPD exacerbations and hospitalisations in the previous year, and sputum colour. Thirty-six patients (62% of those colonised) had a high bacterial load. More than 80% of the sputum samples with a dark yellow or greenish colour yielded PPMs in culture. In contrast, only 5.9% of white and 44.7% of light yellow sputum samples were positive (P < 0.001). Multivariate analysis showed an increased degree of dyspnoea (odds ratio [OR] = 2.63, 95% confidence interval [CI] 1.53-5.09, P = 0.004) and a darker sputum colour (OR = 4.11, 95% CI 2.30-7.29, P < 0.001) as factors associated with the presence of PPMs in sputum. CONCLUSIONS: Almost half of our population of ambulatory moderate to very severe COPD patients were colonised with PPMs. Patients colonised present more severe dyspnoea, and a darker colour of sputum allows identification of individuals more likely to be colonised.

RESUMO

The Spanish registry of alpha-1 antitrypsin deficiency was founded in 1993 and became a member of the International Registry (AIR) in 1999. We describe the updating process following its incorporation into AIR and compare the data collected in the first period (1993-1999) and the second period (1999-2005), during which time patients were included exclusively by internet. The registry included 301 patients during period 1, 69% males and 46% had a history of smoking. Their mean age was 46 years (SD=13) and 284 (94%) had the ZZ phenotype, 49% received augmentation therapy. During period 2, 161 new cases were included, 63% of whom were males with a mean age of 44 years (SD=16). A total of 126 (78%) had the ZZ phenotype. Only 12% received augmentation therapy. A total of 462 different patients were included in both periods. Significant differences were observed in the number of cases with the SZ phenotype and the severity of FEV1 impairment between the two periods. Implementation of an internet-based collection of data did not result in a lower rate of reporting to the registry. However, data from a significant number of patient included in period 1 could not be actualized in the new data base.

RESUMO

Studies undertaken in Spain indicate that 9% of the general population aged between 40 and 70 years is affected by chronic obstructive pulmonary disease (COPD). Although tobacco smoke is the causative factor in more than 90% of cases, it is estimated that only 10% to 20% of smokers develop COPD. This may be explained by the existence of genetic or environmental factors that modulate the toxic effects of tobacco. The best known genetic factor is alpha1-antitrypsin deficiency, which is associated with an increased risk of developing pulmonary emphysema in smokers. The most recent guidelines from both the World Health Organization and the American Thoracic Society/European Respiratory Society recommend the establishment of screening programs for the detection of alpha1-antitrypsin deficiency in patients with COPD. This strategy is crucial in Spain, where the disease is under diagnosed, mainly due to a low index of suspicion among doctors.

RESUMO

Estudios realizados en España señalan que un 9% de la población general de entre 40 y 70 años está afectada de enfermedad pulmonar obstructiva crónica (EPOC). El humo del tabaco es el factor causal en más del 90% de los casos; sin embargo, se ha estimado que sólo un 10-20% de los fumadores desarrollan EPOC. La causa se puede encontrar en la existencia de factores genéticos o ambientales que modulan el efecto tóxico del tabaco. El factor genético más conocido es el déficit de alfa-1-antitripsina, que comporta un riesgo aumentado de desarrollar enfisema pulmonar en fumadores. Tanto la Organización Mundial de la Salud como la American Thoracic Society/European Respiratory Society en sus recientes normativas recomiendan establecer programas de detección del déficit de alfa-1-antitripsina en pacientes con EPOC. Esta estrategia es crucial en España, donde la enfermedad está infradiagnosticada, sobre todo debido a un bajo índice de sospecha entre los médicos

RESUMO

A 39-year-old female patient, an ex-smoker with an 8-pack-year smoking history and severe pulmonary emphysema of early onset, received a diagnosis of alpha(1)-antitrypsin (AAT) deficiency and proved to be a carrier of a new deficient variant, YBARCELONA, derived from the normal M1 variant with two substitutions: one in exon III and the other in exon V. AAT genotype of eight members of the same family and study of lung function of the index case and family members at baseline and after 6 years of follow-up were performed. Five subjects were PiYM, with intermediate serum AAT concentrations and normal pulmonary function. No changes were observed over 6 years in pulmonary function of the PiYM patients who were nonsmokers; however, the PiYY index case presented worsening of pulmonary function with FEV(1) of 33%. The heterozygotes PiYM have AAT concentrations similar to the PiMZ and, at 6 years, the nonsmokers presented no worsening in pulmonary function. The risk associated with this variant in its heterozygous form may be similar to that described for PiMZ.
