Many studies have shown the negative impact of lockdowns on adolescents, but there is less evidence on how they are affected by other stages of the COVID-19 pandemic, and, especially, whether there are any differences between early and late adolescence. The current study focuses on the frustration felt by adolescents because of the severe COVID-19 restrictions in a non-lockdown situation. We aimed to (a) assess the role of maturity and two personality traits (emotional stability and extraversion) in predicting their frustration, and (b) compare the levels of frustration, depressive symptoms, and life satisfaction in older and younger adolescents. The sample of older adolescents was also compared with a paired sample of the same age collected in 2018, before the pandemic. The results suggest that maturity, extraversion and emotional stability are predictors of frustration in both older and younger adolescents, although older adolescents reported higher levels of frustration and depressive symptoms, and lower levels of life satisfaction. Older adolescents also reported higher levels of depressive symptoms than adolescents of the same age before the pandemic. These results show the negative impact of the pandemic, especially on older adolescents, and the important role of maturity and some personality traits in predicting their frustration.

Many studies highlight the importance of parental involvement in the academic performance of children and adolescents across subject areas. In view of the lack of instruments in Spain to assess family involvement of parents of adolescents, we undertook this study to develop the Spanish adaptation of the Family Involvement Questionnaire - High School version (FIQ-HS). The sample consisted of 928 parents (85.7 p females) with adolescent sons and daughters. Exploratory and confirmatory factor analyses substantiated the expected three-factor structure (home-school communication, school-based activities, and home-based activities), though seven poorly functioning items were removed. The results show that this instrument has adequate psychometric properties, good reliability, and convergence with another measure of family adaptability and cohesion. Therefore, the FIQ-HS is adequate for the assessment of family involvement in Spanish parents.

Se llama hidrotórax a una efusión pleural primaria que ocurre durante la vida prenatal (denominado ‘quilotórax primario’ después del nacimiento). En ciertos casos, esta efusión es severa y produce compresión pulmonar y cardiaca, por lo cual, la mortalidad perinatal sigue siendo alta. Los recién nacidos con hidrotórax requieren, muchas veces, de drenaje, nutrición parenteral total y medicación específica para su recuperación. Sin embargo, las intervenciones prenatales, principalmente con derivaciones toraco-amnióticas, pueden mejorar estos resultados. Reportamos el caso de un feto con hidrotórax severo a quien se le realizó una toracocentesis y revisamos la literatura acerca de su rol en el tratamiento prenatal actual.

Children with craniofacial microsomia (CFM) are at increased risk for educational and social concerns. This study describes intervention services and frequency of teasing in a multinational population of children with CFM. Caregivers of children with CFM ages 3 to 18 years in the US and South America were administered a questionnaire. Additional information was gathered from medical charts and photographs. Participants (N = 169) had an average age of 10.1 ± 6.2 years, were primarily male (60%), and from the US (46%) or Colombia (32%). Most participants had microtia and mandibular hypoplasia (70%). They often had unilateral (71%) or bilateral (19%) hearing loss and 53% used a hearing aid. In the US, special education services were provided for 48% of participants enrolled in school; however, similar services were rare (4%) in South America and reflect differences in education systems. Access to any intervention service was higher in the US (80%) than in South America (48%). Caregivers reported children showed diagnosis awareness by an average age of 4.4 ± 1.9 years. Current or past teasing was reported in 41% of the children, starting at a mean age of 6.0 ± 2.4 years, and most often took place at school (86%). As half of the US participants received developmental and academic interventions, providers should screen for needs and facilitate access to services. Given diagnosis awareness at age 4 and teasing at age 6, providers are encouraged to assess for psychosocial concerns and link to resources early in treatment.

ObjectiveOne of the main problems of lung transplantation is the shortage of organs as well as reduced survival rates. In the absence of an international standardized model for lung donor-recipient allocation, we set out to develop such a model based on the characteristics of past experiences with lung donors and recipients with the aim of improving the outcomes of the entire transplantation process.MethodsThis was a retrospective analysis of 404 lung transplants carried out at the Reina Sofía University Hospital (Córdoba, Spain) over 23 years. We analyzed various clinical variables obtained via our experience of clinical practice in the donation and transplantation process. These were used to create various classification models, including classical statistical methods and also incorporating newer machine-learning approaches.ResultsThe proposed model represents a powerful tool for donor-recipient matching, which in this current work, exceeded the capacity of classical statistical methods. The variables that predicted an increase in the probability of survival were: higher pre-transplant and post-transplant functional vital capacity (FVC), lower pre-transplant carbon dioxide (PCO2) pressure, lower donor mechanical ventilation, and shorter ischemia time. The variables that negatively influenced transplant survival were low forced expiratory volume in the first second (FEV1) pre-transplant, lower arterial oxygen pressure (PaO2)/fraction of inspired oxygen (FiO2) ratio, bilobar transplant, elderly recipient and donor, donor-recipient graft disproportion requiring a surgical reduction (Tailor), type of combined transplant, need for cardiopulmonary bypass during the surgery, death of the donor due to head trauma, hospitalization status before surgery, and female and male recipient donor sex.ConclusionsThese results show the difficulty of the problem which required the introduction of other variables into the analysis. The combination of classical statistical methods and machine learning can support decision-making about the compatibility between donors and recipients. This helps to facilitate reliable prediction and to optimize the grafts for transplantation, thereby improving the transplanted patient survival rate.

Ovarian cancer Càncer d'ovari Cáncer de ovario Platinum-based neoadjuvant chemotherapy followed by interval debulking surgery is an accepted treatment for patients with stage III or IV epithelial ovarian cancer who are not suitable for primary debulking surgery. The identification of suitable adjuvant treatments in these patients is an unmet need. Here, we explore potential genomic characteristics (mutational and immune-associated expression profiles) in a series of patients undergoing neoadjuvant chemotherapy. Tumor samples from biopsy and interval debulking surgery were analyzed for mutational landscape and immune profiling, together with detailed immunohistochemistry using different immune cell markers, and correlated with clinicopathological characteristics and potential response to neoadjuvant chemotherapy. No major differences in the mutational landscape were observed in paired biopsy and surgery samples. Genomic loss of heterozygosity was found to be higher in patients with total/near-total tumor response. The immune gene expression profile after neoadjuvant chemotherapy revealed activation of several immune regulation-related pathways in patients with no/minimal or partial response. In parallel, neoadjuvant therapy caused a significant increase of tumor-infiltrating lymphocyte population abundance, primarily due to an augmentation of the CD8+ T cell population. Remarkably, these changes occurred irrespective of potential homologous recombination defects, such as those associated with BRCA1/2 mutations. Our study strengthens the use of loss of heterozygosity as a biomarker of homologous repair deficiency. The changes of immune states during neoadjuvant chemotherapy reveal the dynamic nature of tumor-host immune interactions and suggest the potential use of immune checkpoint inhibitors or their combination with poly-ADP polymerase inhibitors in high stage and grade epithelial ovarian cancer patients undergoing neoadjuvant therapy.

An annotated checklist of the cestode parasites of Argentinean wild birds is presented, as the result of a compilation of parasitological papers published between 1900 and April 2021. This review provides data on hosts, geographical distribution, sites of infection, location of material deposited in helminthological collections, references and taxonomic comments. A host/parasite list is also provided. During this period, 38 papers were published that gather information about 34 cestode nominal species and 11 taxa identified at generic level, belonging to three orders, ten families and 35 genera. The highest number of cestode taxa was recorded in the family Hymenolepididae, with 12 nominal species and two taxa identified at generic level, followed by Dilepididae, with eight nominal species and three taxa identified at generic level. Of the 1042 species of birds reported in Argentina, only 29 (2.8%) were reported as hosts of adult cestodes. The families of birds with the highest number of reported taxa were Laridae and Anatidae, with 20 and 14 taxa, respectively.

Food insecurity is a recurrent condition in which members of a household do not have enough food to cover their nutritional needs; this condition contributes to increasing social vulnerability of those affected. In Peru, there are more than 9 million people who suffer this condition, which generates malnutrition and anemia, mostly in children. On the other hand, the waste of food is associated with production the large amounts of greenhouse gas emissions that affect global warming. According to reports in Peru, 20% of what is food produced becomes waste. This scenario in terms of food for Peruvians represents 3 billion calories in wasted food that could feed 2 million people. The Peruvian Food Bank manages food donations, ensuring this food can reach people in need through humanitarian aid entities. This applied research work uses the tools of operations research to determine a solution to the problem of maximizing the combination of food orders to be distributed based on their total nutritional value to the beneficiaries, seeking maximum coverage and minimum logistic costs.

Background We report the molecular analysis of the DMD gene in a group of Peruvian patients with Duchenne/Becker dystrophinopathy. This is the first study to thoroughly characterize mutations in this population. Methods We used the combination of multiplex ligation‐dependent probe amplification (MLPA) and sequencing analysis of the DMD gene. We recruited Peruvian patients in 2 years from reference national hospitals. We performed DNA tests in 152 patients, checking first exon deletion/duplication by MLPA, and subsequently, if negative, samples were sequenced to detect point mutations. Results The average age for diagnosis was 9.8 years, suggesting a delay for timely diagnosis and care. We found causal DMD mutations in 125 patients: 72 (57.6%) exon deletions/duplications (41.6% deletions, 16.0% duplications), and 53 (42.4%) point mutations (27.2% nonsense, 9.6% small indels, and 5.6% splice site). Conclusion Due to our genetic background, we expected a higher number of novel and recurrent causal mutations in our sample. Results showed 16% of novel mutations, similar to other well‐studied populations., This study characterizes DMD/DMB mutations in Peru. This population has been poorly studied at the genetic level. We want to obtain a landscape of mutations affecting patients and give them treatment options with therapies currently under use in other countries. We found that deletions of the DMD gene, are predominant (41.6%) and point mutations with more than 40% of cases, explain the other cases. Duplications (16%) come in third place in this study. Regarding point mutations, the nonsense type (27%) is the most frequent change found.

Craniofacial microsomia (CFM) is the second most common congenital facial anomaly, yet its genetic etiology remains unknown. We perform whole-exome or genome sequencing of 146 kindreds with sporadic (n = 138) or familial (n = 8) CFM, identifying a highly significant burden of loss of function variants in SF3B2 (P = 3.8 × 10−10), a component of the U2 small nuclear ribonucleoprotein complex, in probands. We describe twenty individuals from seven kindreds harboring de novo or transmitted haploinsufficient variants in SF3B2. Probands display mandibular hypoplasia, microtia, facial and preauricular tags, epibulbar dermoids, lateral oral clefts in addition to skeletal and cardiac abnormalities. Targeted morpholino knockdown of SF3B2 in Xenopus results in disruption of cranial neural crest precursor formation and subsequent craniofacial cartilage defects, supporting a link between spliceosome mutations and impaired neural crest development in congenital craniofacial disease. The results establish haploinsufficient variants in SF3B2 as the most prevalent genetic cause of CFM, explaining ~3% of sporadic and ~25% of familial cases., Despite being a common congenital facial anomaly, the genetic etiology of craniofacial microsomia (CFM) is not well understood. Here, the authors use exome and genome sequencing of 146 individuals with CFM to identify haploinsufficient variants in SF3B2 as a prevalent underlying cause.

Objetivo: identificar los factores asociados a la presencia de fisura labial y/o palatina en recién nacidos en el Hospital Nacional Edgardo Rebagliati Martins, localizado en Lima – Perú, durante el periodo noviembre 2012 - diciembre 2016. Materiales y métodos: estudio observacional, analítico, de casos y controles emparejado, con datos del Estudio Colaborativo Latinoamericano de Malformaciones Congénitas (ECLAMC). Se analizaron 61 casos y 61 controles. La variable dependiente fue la presencia de fisura labial y/o palatina. Se recogieron también variables clínicas, epidemiológicas, obstétricas y prenatales. Resultados: la fisura labiopalatina con extensión completa, en el sexo masculino, fue la forma más frecuente y estuvo presente en 36 neonatos (59%), con cariotipo normal 44 (75,9%) y sin diagnóstico prenatal 40 (65,6%). Las malformaciones observadas con más frecuencia fueron las faciales 27 (44,2%) seguidas de malformaciones cardiacas (29,6%). Se construyó un modelo estadístico mediante análisis multivariado conformado por tres variables: enfermedad crónica durante el embarazo (odds ratio [OR]: 3,8; intervalo de confianza al 95% [IC 95%]: 1,11 - 13,08), edad materna mayor a 35 años (OR: 6,85; IC 95%: 2,69 - 17,43) y antecedente familiar (OR: 14,5; IC 95%: 1,68 - 125,56). Conclusiones: las enfermedades crónicas en el embarazo, la edad materna avanzada y el antecedente familiar fueron factores que aumentaron la presencia de fisura labial y/o palatina.

Background Craniofacial microsomia (CFM), also known as the oculo‐auriculo‐vertebral spectrum, comprises a variable phenotype with the most common features including microtia and mandibular hypoplasia on one or both sides, in addition to lateral oral clefts, epibulbar dermoids, cardiac, vertebral, and renal abnormalities. The etiology of CFM is largely unknown. The MYT1 gene has been reported as a candidate based in mutations found in three unrelated individuals. Additional patients with mutations in this gene are required to establish its causality. We present two individuals with CFM that have rare variants in MYT1 contributing to better understand the genotype and phenotype associated with mutations in this gene. Methods/Results We conducted genetic analysis using whole‐exome and ‐genome sequencing in 128 trios with CFM. Two novel MYT1 mutations were identified in two participants. Sanger sequencing was used to confirm these mutations. Conclusion We identified two additional individuals with CFM who carry rare variants in MYT1, further supporting the presumptive role of this gene in the CFM spectrum., We conducted genetic analysis using whole‐exome and ‐genome sequencing in 128 trios with CFM. Two novel MYT1 mutations were identified in two participants, further supporting the presumptive role of this gene in the CFM spectrum.

Peru is a pluricultural and ethnically diverse country located in middle west of South America. It is the fourth largest country (1,285,216 km2) in area in South America, bordered in the north by Ecuador and Colombia, in the south by Chile, south east by Bolivia, by Brazil in the east and by the Pacific Ocean in the west. Peru has one of the most diverse climates, geographical and ecological in the world, from tropical or subtropical dessert to glacial in highland mountains to Amazon jungle. Peru is divided into 24 geopolitical regions with a central government. According to last national census in 2017, Peruvian populations accounts for 31,237,385 inhabitants (Instituto Nacional de Estadistica e Informatica [INEI], 2017). Most of Peru's population lives in the Coastal area, with almost one third of the nation's population living in Lima, the largest city with approximately 11 million people. Rural and urban population has changed over the last 50 years due to migration waves in the 1950s from rural to urban sites mainly located in the coast causing decrease or disappearance of native communities.

Very few studies have examined whether the degree of adolescents' maturity has any effect on their academic performance. Moreover, there are no studies that show whether maturity explains variance additional to that explained by intelligence and personality. For this reason, the main aim of the current study was to determine how psychological maturity, the Big Five personality traits and mental aptitudes contribute to the prediction of adolescent academic performance.305 adolescents took part in the study. We performed correlations, multiple regression analysis and structural equation analysis.As expected, results show that the main predictor is intelligence. The results also show that there is a relationship between psychological maturity and academic performance, although this is due only to the work orientation subscale. Moreover, conscientiousness influences academic performance because of its relation to the maturity factor work orientation. Likewise, openness to experience is also indirectly related to academic performance, due to its relationship with intelligence.The results of the current study suggest that psychological maturity is related to academic performance. Only two personality traits are correlated to academic performance, conscientiousness and openness to experience, although these traits do not have direct relationships with academic performance.

Hereditary Hemorrhagic Telangiectasia (HHT) is a rare disorder of vascular development. Common manifestations include epistaxis, telangiectasias and arteriovenous malformations (AVMs) in multiple organs. Most patients have deletions or missense mutations in the ENG or ACVRL1 gene respectively, significantly affecting endothelium homeostasis. We analyzed the ENG gene in five members of a Peruvian family affected by HHT. One novel mutation was found in exon four of the ENG gene c.408delA, at aminoacid residue 136. This mutation changes the subsequent reading frame producing an early stop at residue 162, preserving only one fourth of the normal protein of 658 aa. This mutation was found in the four affected members of family.

Turner syndrome (TS) is a common multiple congenital anomaly syndrome resulting from complete or partial absence of the second X chromosome. TS presents with short stature, infertility secondary to ovarian dysgenesis, cardiac and renal anomalies, characteristic exam findings such as cubitus valgus, normal intelligence, and specific neurocognitive profile which includes visual spacial deficits and math difficulties. Clinical studies of TS have predominantly focused on individuals of European descent. In this study, we explore the phenotype of TS in diverse populations using clinical examination and facial analysis technology. Clinical data from 70 individuals and images from 108 individuals with TS from 18 different countries were analyzed. Individuals were grouped into categories of African descent (African), Asian, Latin American, Caucasian (European descent), and Middle Eastern. The most common phenotype features across all population groups were short stature (85%), cubitus valgus (77%) and, low posterior hair line 70%. Other phenotype features found in over half included small mandible (63%), narrow hyperconvex and deep set fingernails (56%), narrow maxilla (53%), and short fourth metacarpals (50%). Congenital heart disease was found in 32% of the cohort. Two facial analysis technology experiments were conducted: TS vs. general population and TS vs. Noonan syndrome. Across all ethnicities, facial analysis was very accurate in diagnosing TS from frontal facial images as measured by the area under the curve (AUC). An AUC of 0.903 (p

Biological control with Cryphonectria hypovirus CHV1 of the chestnut blight, caused by the fungus Cryphonectria parasitica, has reduced the impact of the disease in Europe. The virus reduces the virulence of the fungus so that it causes non-lethal cankers, thus enabling the chestnut trees to overcome the disease. The virus can be transmitted horizontally by hyphal anastomosis or vertically to the conidia. In this study, we investigated growth and sporulation of the fungus as well as rates of horizontal transmission of the virus at different temperatures. We used fungal isolates of the vegetative compatibility types (vc types) that are most prevalent in Castilla and Leon (central northern Spain) to evaluate the effects of fungal strain on the parameters tested. In addition, we infected four isolates of C. parasitica with hypovirus subtypes CHV1-F1 and CHV1-I, to determine the influence of virus subtype on growth, sporulation and virus transfer. We assessed growth of fungal colonies and horizontal transmission of the virus at 15 °C and 25 °C. Colony growth was affected by an interaction between fungal isolates included in vc type EU1 or EU11 and virus at both 15 °C and 25 °C. However, horizontal transmission of the virus was only influenced by the fungal genotype of isolates included in vc type EU1 or EU11, and spore production was only affected by the virus subtype. Vertical transmission was also influenced by the fungal isolate and virus subtype. Growth of the fungal isolates varied depending on the virus subtype with which they were infected. This supports the theory that fungal host and virus subtype influence transmission and dissemination of hypovirulence. The fungal genotype affects colony growth and horizontal transmission of the virus. It is common to expect a good dissemination of the hypovirus with a low vc type diversity but the selection of the best combination of hypovirus and fungal isolate is crucial for the success of biological control not only for small areas but in larger chestnut populations as well.

Maintenance during industrial development has evolved, always seeking the in-depth study of the physical phenomena that occur in the elements and systems that have suffered functional failures. Maintenance has been adapted to each challenge presented. The progress and development of computer science have opted for the massive use of information and communication technologies that support industrial processes, generating new possibilities in maintenance management and operation. These tools could contribute to improving the efficiency of maintenance processes, taking into account that these costs represent a third of the total production cost in an organization. This work seeks to identify the evolution of these technological tools in the applications that they have had in representing the physical phenomena of maintenance management. This research also seeks to establish the minimum requirements that these tools must consider in their applications and uses. Considering the appropriation of these technologies in Colombia, in order to determine where the country is in terms of development and technological use, being important information for the recognition of the scenario and decision-making that prevail in a competitive Colombian industry world level.
