RESUMO

Stress is a condition that has been related to the development of risk behaviors for health such as sugar-sweetened beverages (SSBs) consumption. The aim of this study was to examine the link between SSBs consumption and perceived stress level in university students. This was an observational, cross-sectional and single-time-point study where the subjects were recruited as a non-probabilistic sample of first-year university students. The students reported their SSBs consumption through a validated questionnaire, as well as their perceived stress level, evaluated through the Cohen scale. Comparisons were made between the means of all variables. Factorial analysis of variance was conducted to explore the effect of the variables' interaction on the stress level. One-way analysis of variance was performed to assess differences between the sexes. Men consumed more SSBs (6101.17 ± 3772.50 mL/week) compared to women (4294.06 ± 3093.8 mL/week). However, women had higher scores of perceived stress and showed a strong association of stress with the SSBs consumption pattern (r and p-value). This study shows for the first time the association that exists between stress and SSBs consumption and indicates that it is related to sex in the young population.

RESUMO

BACKGROUND: Glioblastoma is the most common and devastating primary brain cancer. Radiotherapy is standard of care; however, it is associated with brain radiation toxicity (BRT). This study used a multi-omics approach to determine whether BRT-related genes (RGs) harbor survival prognostic value and whether their encoded proteins represent novel therapeutic targets for glioblastoma. METHODS: RGs were identified through analysis of single-nucleotide variants associated with BRT (R-SNVs). Functional relationships between RGs were established using Protein-Protein Interaction networks. The influence of RGs and their functional groups on glioblastoma prognosis was evaluated using clinical samples from the Glioblastoma Bio-Discovery Portal database and validated using the Chinese Glioma Genome Atlas dataset. The identification of clusters of radiotoxic and putative pathogenic variants in proteins encoded by RGs was achieved by computational 3D structural analysis. RESULTS: We identified the BRT-related 15CAcBRT molecular signature with prognostic value in glioblastoma, by analysis of the COMT and APOE protein functional groups. Its external validation confirmed clinical relevance independent of age, MGMT promoter methylation status, and IDH mutation status. Interestingly, the genes IL6, APOE, and MAOB documented significant gene expression levels alteration, useful for drug repositioning. Biological networks associated with 15CAcBRT signature involved pathways relevant to cancer and neurodegenerative diseases. Analysis of 3D clusters of radiotoxic and putative pathogenic variants in proteins coded by RGs unveiled potential novel therapeutic targets in neuro-oncology. CONCLUSIONS: 15CAcBRT is a BRT-related molecular signature with prognostic significance for glioblastoma patients and represents a hub for drug repositioning and development of novel therapies.

RESUMO

Few studies have addressed how selective pressures have shaped the genetic structure of the current Native American populations, and they have mostly limited their inferences to admixed Latin American populations. Here, we searched for local adaptation signals, based on integrated haplotype scores and population branch statistics, in 325 Mexican Indigenous individuals with at least 99% Native American ancestry from five previously defined geographical regions. Although each region exhibited its own local adaptation profile, only PPARG and AJAP1, both negative regulators of the Wnt/ß catenin signaling pathway, showed significant adaptation signals in all the tested regions. Several signals were found, mainly in the genes related to the metabolic processes and immune response. A pathway enrichment analysis revealed the overrepresentation of selected genes related to several biological phenotypes/conditions, such as the immune response and metabolic pathways, in agreement with previous studies, suggesting that immunological and metabolic pressures are major drivers of human adaptation. Genes related to the gut microbiome measurements were overrepresented in all the regions, highlighting the importance of studying how humans have coevolved with the microbial communities that colonize them. Our results provide a further explanation of the human evolutionary history in response to environmental pressures in this region.

RESUMO

Gliomas are the deadliest of all primary brain tumors, and they constitute a serious global health problem. MicroRNAs (miRNAs) are gene expression regulators associated with glioma pathogenesis. Thus, miRNAs represent potential therapeutic agents for treating gliomas. However, miRNAs have not been established as part of the regular clinical armamentarium. This systemic review evaluates current molecular and pre-clinical studies with the aim of defining the most appealing supramolecular platform for administering therapeutic miRNA to patients with gliomas. An integrated analysis suggested that cationic lipid nanoparticles, functionalized with octa-arginine peptides, represent a potentially specific, practical, non-invasive intervention for treating gliomas. This supramolecular platform allows loading both hydrophilic (miRNA) and hydrophobic (anti-tumor drugs, like temozolomide) molecules. This systemic review is the first to describe miRNA delivery systems targeted to gliomas that integrate several types of molecules as active ingredients. Further experimental validation is warranted to confirm the practical value of miRNA delivery systems.

RESUMO

BACKGROUND/OBJECTIVES: Neck circumference (NC) has been used for screening overweight/obesity for its high correlation with age, weight, body mass index (BMI), and waist circumference (WC). Cut-offs should be population specific. The aim of the study was to obtain cut-offs of NC for overweight/obesity in Mexican adolescents and to correlate them with anthropometric indicators. SUBJECTS/METHODS: Weight, height, BMI, NC, WC, and mid-upper arm circumference (MUAC) of 465 12-14-year-old Mexican-mestizo students attending a public school in Mexico City were assessed. Using receiver operating characteristics analyses, neck cut-offs were obtained according to the WHO age and sex criteria for overweight/obesity. RESULTS: NC cut-offs with the highest sensitivity and specificity for males and females, respectively, were as follows: 30.0 and 29.3 cm for 12-year-olds; 31.9 and 30.4 cm for 13-year-olds; and, 33.5 and 30.7 cm for 14-year-old adolescents. Overweight/obesity was identified with NC cut-offs in 80% of males and 86% of females, and showed significant correlations (p < 0.01) in males and females with weight (r = 0.821 and r = 0.840, respectively), BMI (r = 0.649 and r = 0.819, respectively), WC (r = 0.710 and r = 0.813, respectively) and MUAC (r = 0.736 and r = 0.815, respectively). CONCLUSIONS: Neck circumference may be used as a first-stage screening tool or jointly with BMI to identify overweight/obesity in 12-14-year-old Mexican adolescents.

Abstract Hemophilia is a hemorrhagic disorder with a sex-linked inherited pattern, characterized by an inability to amplify coagulation due to a deficiency in coagulation factor VIII (hemophilia A or classic) or factor IX (hemophilia B). Sequencing of the genes involved in hemophilia has provided a description and record of the main mutations, as well as a correlation with the various degrees of severity. Hemorrhagic manifestations are related to levels of circulating factor, mainly affecting the musculoskeletal system and specifically the large joints (knees, ankles and elbows). This document is a review and consensus of the main genetic aspects of hemophilia, from the inheritance pattern to the concept of women carriers, physiopathology and classification of the disorder, the basic and confirmation studies when hemophilia is suspected, the various treatment regimens based on infusion of the deficient coagulation factor as well as innovative factor-free therapies and recommendations for the management of complications associated with treatment (development of inhibitors and/or transfusion transmitted infections) or secondary to articular hemorrhagic events (hemophilic arthropathy). Finally, relevant reviews of clinical and treatment aspects of hemorrhagic pathology charachterized by acquired deficiency of FVIII secondary to neutralized antibodies named acquired hemophilia.

RESUMO

Resumen: La ligadura de una rama de la vena porta constituye un procedimiento con buenos resultados para evitar la falla hepática posoperatoria en caso de hepatectomías extremas al provocar la hipertrofia del hígado contralateral. Sin embargo, la repermeabilización de ésta ha sido demostrada por la presencia de anastomosis porto portales intrahepáticas, pudiendo determinar una disminución de la hipertrofia esperada o necesaria. Como objetivo documentamos un caso clínico de repermeabilización intrahepática de la vena porta, evento no deseado de la hepatectomía en dos tiempos para el tratamiento de metástasis hepáticas bilobares de origen colorrectal y describimos alternativas para evitar o tratar dicha repermeabilización.

Summary: Left or right portal vein ligation to prevent post-operative liver failure in the case of extreme hepatectomy constitutes a procedure with a good prognosis, as it causes contralateral liver hypertrophy. However, its revascularization has been proved by intrahepatic porto-portal anastomoses, which could result in a reduction of the expected or required hypertrophy. The study aims to record a clinical case of intrahepatic revascularization of the portal vein, an unwanted event of the two-stage hepatectomy to treat bilobar hepatic metastasis of colorectal origin, and describe alternatives to avoid or treat such revascularization.

Resumo: A ligadura de um ramo da veia porta é um procedimento com bons resultados para evitar a insuficiência hepática pós-operatória em hepatectomias extremas por causar hipertrofia do fígado contralateral. No entanto, sua repermeabilização tem sido demonstrada pela presença de anastomose porto-portal intra-hepática, que pode determinar diminuição da hipertrofia esperada ou necessária. Como objetivo, documentamos um caso clínico de repermeabilização da veia porta intra-hepática, um evento indesejado de hepatectomia em dois estágios para o tratamento de metástases hepáticas bilobares de origem colorretal, e descrevemos alternativas para evitar ou tratar essa repermeabilização.

RESUMO

Objectives: The Dominican Republic lacks reliable information on antimicrobial resistance (AMR), which would allow physicians to prescribe the best treatment for common infectious diseases. This study aimed to define the antimicrobial resistance profiles of the more common pathogens from pediatric services, where data is even more important due to the vulnerability of the population. Methods: We collected data from patients admitted in the pediatric unit of three third level hospitals in the city of Santiago de los Caballeros, Dominican Republic, showing positive bacterial cultures, during a period of two years. Results: Half of the Gram negative pathogens exhibited third generation cephalosporins (3GC) resistance, 17% were resistant to carbapenems. Serratia marcescens presented an exceptionally high proportion of resistance to 3GC (95.9%). Staphylococcus aureus showed elevated resistance to methicillin (58.4%) and even to clindamycin (35.8%). Conclusion: There are elevated levels of antimicrobial resistance among the Enterobacteriaceae family and the Staphylococcus genus isolated from the pediatric population. Necessary measures should be taken to tackle AMR in the country.

RESUMO

Resumen La epidemia de nacimientos prematuros es fruto de la compleja interacción entre los factores genéticos, sociales y ambientales. Gracias a los avances tecnológicos, la supervivencia de prematuros de menor edad y peso se ha incrementado, así como el riesgo de las secuelas que ello puede provocar. Este trabajo busca caracterizar los factores ambientales y sociales que pueden afectar el neurodesarrollo; el análisis se realizó en un modelo de intervención temprana en el Instituto Nacional de Pediatría (INP). Se presenta el reporte de un caso de embarazo múltiple asistido donde los factores genéticos y ambientales fueron similares, con diferencias en los factores biológicos, así como la interacción de la díada y su evolución en el neurodesarrollo durante el primer año de vida.

Abstract The premature birth epidemic is the result of genetic, social and environmental complex interactions. As smaller and lower-weight children survive, sequelae increase. This paper characterizes the environmental and social factors related to neurodevelopment as a component of an early intervention program at the National Pediatrics Institute. We present the case report of an assisted multiple pregnancy with similar genetic and environmental factors, but biologic and dyadic interaction differences, and report the neurodevelopmental evolution over the first year of life.

RESUMO

Huanglongbing (HLB) constitutes the most destructive disease of citrus worldwide, yet no established efficient management measures exist for it. Brassinosteroids, a family of plant steroidal compounds, are essential for plant growth, development and stress tolerance. As a possible control strategy for HLB, epibrassinolide was applied to as a foliar spray to citrus plants infected with the causal agent of HLB, 'Candidatus Liberibacter asiaticus'. The bacterial titers were reduced after treatment with epibrassinolide under both greenhouse and field conditions but were stronger in the greenhouse. Known defense genes were induced in leaves by epibrassinolide. With the SuperSAGE technology combined with next generation sequencing, induction of genes known to be associated with defense response to bacteria and hormone transduction pathways were identified. The results demonstrate that epibrassinolide may provide a useful tool for the management of HLB.

RESUMO

The standard approach to the follow-up of lymphoma includes computed tomography (CT) every 6-12 months for the first 2 years and, then, as clinically indicated. Recent evidence suggests that most relapses are detected clinically, outside scheduled CT which, on the other hand, increases risk of second malignancies and cost. In early-stage lymphomas, involved site CT instead of full body CT may be a reasonable alternative to reduce radiation dose. We analyzed whether regular CT surveillance detects asymptomatic relapses in a single-center Uruguayan early stage non-Hodgkin lymphoma (NHL) population. We evaluated utility of full body CT halfway and at the end-of-treatment evaluation and calculated the radiation exposure. In our study, CT surveillance added nothing to clinical follow-up. Moreover, 44% of our patients received a cumulative effective dose that doubles the risk of malignancies. Involved-site CT scan would be enough to monitor response during treatment in early stage NHL.

RESUMO

OBJETIVO: Avaliar as alterações posturais e de amplitudes de movimento de membro superior nas mulheres pós-mastectomia e linfadenectomia que se submeteram à radioterapia como tratamento adjuvante. MÉTODOS: Foram avaliados dois grupos: 16 mulheres pós-mastectomia com linfedema de membro superior e 14 mulheres pós-mastectomia sem linfedema. As pacientes foram submetidas à avaliação feita por programas computadorizados, um para postura e outro para medir as amplitudes de movimento de ombro, cotovelo e punho. Os resultados obtidos foram comparados entre lado direito e esquerdo, e operado e não operado, sendo submetidos a testes estatísticos. RESULTADOS: Ambos os grupos apresentaram anteriorização de tronco. As mulheres com linfedema mostraram rotação de cabeça à direita, protusão de ombro do lado esquerdo e medidas do ângulo de talhe menores do lado operado, além de elevação da escápula bilateralmente, quando comparadas ao grupo sem linfedema. As alterações de amplitude de movimento também foram menores do lado operado na flexão, abdução e rotação externa de ombro para todas as mulheres e, para aquelas que tinham linfedema, a extensão de cotovelo e a flexão de punho tiveram menor amplitude de movimento. CONCLUSÃO: Mulheres que foram submetidas à mastectomia apresentaram assimetrias e alterações de postura, e o linfedema parece agravar essa condição. Além disso, apresentaram déficits de amplitude de movimento em ombros, do lado operado. Mulheres com linfedema exibiram também déficits em cotovelo e punho.

OBJECTIVE: To evaluate alterations in posture and range of motion of the upper limbs in women after mastectomy and lymphadenectomy, submitted to radiotherapy as adjuvant treatment. METHODS: Two groups were evaluated: 16 post-mastectomy women with lymphedema of the upper limb and 14 post-mastectomy women without lymphedema. Patients were submitted to analysis made by software, one for posture and the other to measure ranges of movement of the shoulder, elbow, and wrists. The results obtained were compared between the right and left sides, and operated and non-operated sides, and then were submitted to statistical tests. RESULTS: Both groups presented with anteriorization of the trunk. The women with lymphedema had head rotation to the right, protrusion of the left shoulder, and trunk inclination angle smaller on the operated side, besides bilateral elevation of the scapula when compared to the group with no lymphedema. Changes in range of motion were also smaller on the operated side in terms of flexion, abduction, and external rotation of the shoulder for all women, and for those with lymphedema, elbow extension and wrist flexion had a smaller range of motion. CONCLUSION: Women submitted to mastectomy presented with asymmetries and modifications in posture, and lymphedema seemed to worsen this condition. Additionally, they had deficits in range of motion in the shoulders on the operated side. Women with lymphedema also showed deficits in the elbows and wrist.

CONCLUSION: Women submitted to mastectomy presented with asymmetries and modifications in posture, and lymphedema seemed to worsen this condition. Additionally, they had deficits in range of motion in the shoulders on the operated side. Women with lymphedema also showed deficits in the elbows and wrist.

RESUMO

BACKGROUND: Traditional volumetry based on Archimedes' principle is the gold standard for the measurement of limb volume, but the routine use of this technique is discouraged because of several disadvantages. OBJECTIVE: The purpose of this study was to evaluate intraobserver and interobserver reliability of direct measurements of wrist-hand volume using a new communicating vessels volumeter based on Pascal's law. DESIGN: A reliability study was conducted. METHODS: To evaluate the reliability of the communicating vessels volumeter in generating measurements, 30 hands of 15 participants (9 women, 6 men) were measured 3 times each by 3 observers, totaling 270 volumetric results. RESULTS: Measurement time was short (X =3 minutes 42 seconds). The intraclass correlation coefficient (ICC) was .9977 for observer 1 and .9976 for observers 2 and 3. The interobserver ICC was .9998. The standard error of measurement was about 3 mL for all observers; the interobserver result was 1 mL. The interrater coefficient of variance (CV) was 1.15% for the series of 9 measurements collected for each segment; the intrarater CV was 1.20%. Limitations No swollen hands were measured, and measurements were not compared with the gold standard technique. Thus, accuracy of the new volumeter was not determined in this study. CONCLUSION: A new device has been developed for plethysmography of the extremities, and the results of its use to measure the volume of the wrist-hand segment were reliable in both intraobserver and interobserver analyses.
