ABSTRACT
OBJECTIVE: A cross-sectional study was conducted (2012-2013) to evaluate the prevalence of 1) malocclusion and 2) occlusal characteristics in 13- to 18-yearold adolescents in San Juan, Puerto Rico (PR) from selected high schools in the municipality of San Juan. METHODS: The study sample consisted of 155 adolescents. The University of Puerto Rico's IRB approved the study and consent and assent were completed for or by each participant, as applicable. A calibrated dentist performed a single-visit dental evaluation at each school. Occlusal characteristics were measured and recorded according to the criteria reported in the US National Health and Nutrition Examination Survey (NHANES III) and included overjet, overbite, anterior and posterior crossbites, incisor irregularity, maxillary midline diastema and Angle's classification. Descriptive and inferential statistical analyses were performed using SAS statistical software. RESULTS: The mean age of the study subjects was 16 (±1.2) years; all subjects (100%) presented at least 1 abnormal occlusal trait. The most frequent anomaly noted was maxillary malalignment (83%), followed by lower incisor irregularity and excessive overbite (79%) and excessive overjet (63%); the least common occlusal trait was open bite (1.9%). Compared by gender, no statistically significant difference was observed for any variable (p = 0.05). Seventy-three percent (73%) of the subjects presented with Class I malocclusion, 7.1% with Class II malocclusion and 19.4% with Class III malocclusion. CONCLUSION: A high prevalence of malocclusion was observed in this group of adolescents, highlighting the need to implement preventive measures to improve oral health in this population.

Extracellular vesicles (EVs) are defined as subcellular structures limited by a bilayer lipid membrane that function as important intercellular communication by transporting active biomolecules, such as proteins, amino acids, metabolites, and nucleic acids, including long non-coding RNAs (lncRNAs). These cargos can effectively be delivered to target cells and induce a highly variable response. LncRNAs are functional RNAs composed of at least 200 nucleotides that do not code for proteins. Nowadays, lncRNAs and circRNAs are known to play crucial roles in many biological processes, including a plethora of diseases including cancer. Growing evidence shows an active presence of lnc- and circRNAs in EVs, generating downstream responses that ultimately affect cancer progression by many mechanisms, including angiogenesis. Moreover, many studies have revealed that some tumor cells promote angiogenesis by secreting EVs, which endothelial cells can take up to induce new vessel formation. In this review, we aim to summarize the bioactive roles of EVs with lnc- and circRNAs as cargo and their effect on cancer angiogenesis. Also, we discuss future clinical strategies for cancer treatment based on current knowledge of circ- and lncRNA-EVs.
ABSTRACT
Cancer is responsible for more than 10 million deaths every year. Metastasis and drug resistance lead to a poor survival rate and are a major therapeutic challenge. Substantial evidence demonstrates that an increasing number of long non-coding RNAs are dysregulated in cancer, including the long intergenic non-coding RNA, regulator of reprogramming (linc-ROR), which mostly exerts its role as an onco-lncRNA acting as a competing endogenous RNA that sequesters micro RNAs. Although the properties of linc-ROR in relation to some cancers have been reviewed in the past, active research appends evidence constantly to a better comprehension of the role of linc-ROR in different stages of cancer. Moreover, the molecular details and some recent papers have been omitted or partially reported, thus the importance of this review aimed to contribute to the up-to-date understanding of linc-ROR and its implication in cancer tumorigenesis, progression, metastasis, and chemoresistance. As the involvement of linc-ROR in cancer is elucidated, an improvement in diagnostic and prognostic tools could promote and advance in targeted and specific therapies in precision oncology.
ABSTRACT
PURPOSE: To evaluate the effect of three concentrations of bismuth trioxide (Bi2O3) on the biological and physicochemical properties of an experimental mineral trioxide aggregate-type (MTA-type) cement at different time points. METHODS: Three experimental groups with white Portland cement containing 15, 20, or 25 wt% of Bi2O3 were assessed. Cellular proliferation in human periodontal ligament fibroblasts was evaluated with an MTT assay. Radiopacity, dimensional stability, pH, and compressive strength were evaluated at different time points. RESULTS: Bismuth trioxide induced cell proliferation in the Bi15 and Bi25 groups in a time-dependent manner; pH was similar in all groups. Compressive strength was associated with time and bismuth concentration. Bi25 had significantly contracted at day 7 and expanded at day 14 (ANOVA P < 0.05, post hoc Tukey test P < 0.05). CONCLUSION: A higher Bi2O3 concentration had a negative effect on the physical properties of the cement at all time points.

Resurrecting extinct species is a fascinating and challenging idea for scientists and the general public. Whereas some theoretical progress has been made for animals, the resurrection of extinct plants (de-extinction sensu lato) is a relatively recently discussed topic. In this context, the term 'de-extinction' is used sensu lato to refer to the resurrection of 'extinct in the wild' species from seeds or tissues preserved in herbaria, as we acknowledge the current impossibility of knowing a priori whether a herbarium seed is alive and can germinate. In plants, this could be achieved by germinating or in vitro tissue-culturing old diaspores such as seeds or spores available in herbarium specimens. This paper reports the first list of plant de-extinction candidates based on the actual availability of seeds in herbarium specimens of globally extinct plants. We reviewed globally extinct seed plants using online resources and additional literature on national red lists, resulting in a list of 361 extinct taxa. We then proposed a method of prioritizing candidates for seed-plant de-extinction from diaspores found in herbarium specimens and complemented this with a phylogenetic approach to identify species that may maximize evolutionarily distinct features. Finally, combining data on seed storage behaviour and longevity, as well as specimen age in the novel 'best de-extinction candidate' score (DEXSCO), we identified 556 herbarium specimens belonging to 161 extinct species with available seeds. We expect that this list of de-extinction candidates and the novel approach to rank them will boost research efforts towards the first-ever plant de-extinction.

INTRODUCTION: Humour plays an important role in promoting successful and healthy aging. However, its scientific study is still limited, partly due to the absence of validated tools for use in Latin America. The objective of this study was to translate the 5-item Coping with Humor Scale (CHS-5) from English to Spanish and examine the evidence of reliability and validity based on the internal, convergent, and discriminant structure of the Peruvian version of the scale. MATERIALS AND METHOD: The participants were 236 elderly Peruvian adults (78.4% A confirmatory factor analysis, analysis of correlation (r), and reliability (α, Cronbach's alpha and ω, omega) was performed. RESULTS: The one-dimensional model presented an adequate fit of the data (χ2 = 7.72, df =5, P=.17, χ2 / df = 1.54, GFI = 0.988, CFI = 0.996, NFI = 0.988, RMSEA =0. 048 [95% CI; 0.000-0.111]; and SRMR = 0.016). The reliability indexes were adequate (α= 0.86 [95% CI: 0.82-0.89] and ω = 0.89 [95% CI: 0.87-0.91]). A positive correlation was observed between the mean score of CHS-5 and satisfaction with life, and was negative with depression. CONCLUSIONS: The CHS-5 has excellent psychometric properties, being a measure that provides valid and reliable interpretations to be used in elderly Peruvians with depression.

INTRODUCCIÓN: La formación del alumno de medicina es dinámica y multifactorial, requiere de entrenamiento constante con los recursos necesarios bajo la tutela de un profesor clínico que le guíe a desarrollar su máximo potencial. El objetivo de esta investigación fue diseñar y validar un instrumento que permita conocer la percepción de los alumnos sobre la calidad de los campos clínicos donde participan en sus rotaciones. MATERIAL Y MÉTODOS: Es un estudio de tipo cuantitativo, observacional, descriptivo, prospectivo y transversal. La población participante fueron los 148 alumnos del quinto año de la carrera de medicina de una universidad privada al norte de México. Se elaboró una herramienta de 30 ítems que evalúa la calidad de los campos clínicos en tres variables: estructura, tutoría, y proceso enseñanza-aprendizaje, en una escala Likert de 4 niveles que va desde 1, totalmente en desacuerdo, a 5, totalmente de acuerdo. Para el estudio se considera el análisis de ítem para evaluar la consistencia interna, así como la prueba ANOVA, prueba Tukey, y estadística descriptiva para estudiar las tendencias por factores y por servicio. RESULTADOS: Se obtuvo un alfa de Cronbach de 0,9549. La media del factor de estructura fue 3,64, la media de tutoría fue 4,03 y la de proceso enseñanza-aprendizaje, 4,18. El servicio que recibió una evaluación más favorable fue Pediatría, obteniendo una diferencia significativa en los elementos de estructura (p = 0,008) y tutoría (p = 0,003). DISCUSIÓN: Aunque la media observada en la percepción de los alumnos indica un nivel adecuado de la tutoría y el proceso de enseñanza aprendizaje, al hacer un análisis por sede se observa una amplia variación de la calidad de enseñanza ofrecida. Como instituciones educativas esto es un foco de atención porque significa que los alumnos no adquieren ni desarrollan sus competencias de igual manera en todos los campos clínicos
INTRODUCTION: Medical student training is dynamic and multifactorial. It requires continuing education and training under the tutelage of a clinic professor, who will guide the student to develop optimal potential. The objective of this study was to design and validate a tool to measure student perception on the learning quality of clinical rotations. MATERIAL AND METHODS: The study is quantitative, observational, descriptive, prospective, and cross-sectional. The study sample was consisted of 148 fifth-year medical students from a private university in northern Mexico. A 30 item questionnaire was developed to assess quality of clinical stewardships in three variables: structure, tutoring, and teaching-learning process. A five-level Likert scale from 1, absolutely disagree, to 5, absolutely agree, was used. The study used item analysis to estimate internal consistency, as well as ANOVA, Tukey and descriptive statistics to assess the tendencies by factors and stewardship. RESULTS: Cronbach alpha was 0.9549. The structure factor mean was 3.64, tutoring 4.03, and teaching-learning process 4.18. Paediatrics received the most favourable evaluation by obtaining a significant difference in the element structure (P=.008) and tutoring (P=.003). DISCUSSION: Even though the mean observed among tutoring and teaching-learning process indicates an adequate level of student perception, under the analysis per field, a significant variation was found in the quality of learning experience. As an academic institution, this is a concern because students are not acquiring or developing the same level of skills in all stewardships

Resumen El estudio examina las evidencias psicométricas de la Escala de Autoeficacia para Envejecer (EAEE) en una muestra de 400 adultos mayores (75.2% mujeres y 24.8% hombres) de la ciudad de Trujillo (Perú) con una edad promedio de 73.37 años (DE = 7.86). Los participantes completaron la EAEE junto con medidas de satisfacción con la vida y depresión. El análisis factorial exploratorio (AFE), reveló que la EAEE presentaba una estructura factorial unidimensional. El análisis factorial confirmatorio (AFC), mostró que el modelo unidimensional tenía un ajuste aceptable (S-Bχ2 = 54.02, df = 345 p = .001; S-Bχ2/df = 1.54; CFI = .97; RMSEA = .052 [IC90% .021, .078]; y SRMR = .049; AIC= 118.96) y una confiabilidad adecuada (ω = .88 [IC95% .84 - .91]; α = .88 [IC95%: .84 - .91]). Los puntajes de la EAEE se correlacionaron de manera positiva con la satisfacción con la vida (r = .56, p< .01 [IC95%: .46, .79]) y negativa con la depresión (r = -.48, p< .01 [IC95%: -.37, -.73]). Los resultados sugieren que la EAEE presenta evidencias de validez basada en la estructura interna, convergente y discriminante, así como una adecuada confiabilidad.
Abstract The study examines the psychometric evidences of the Self-Efficacy Scale for Aging (EAEE) in a sample of 400 older adults (75.2% women and 24.8% men) from the city of Trujillo (Peru) with an average age of 73.37 years (DE = 7.86). The participants completed the EAEE along with measures of life satisfaction and depression. The exploratory factor analysis (AFE) revealed that the EAEE presented a one-dimensional factorial structure. The confirmatory factor analysis (CFA) showed that the one-dimensional model had an acceptable fit (S-Bχ2 = 54.02, df = 345 p = .001; S-Bχ2/df = 1.54; CFI = .97; RMSEA = .052 [IC90% .021, .078]; y SRMR = .049; AIC= 118.96) and an adequate reliability (ω = .88 [IC95% .84 - .91]; α = .88 [IC95%: .84 - .91]). EAEE scores correlated positively with satisfaction with life (r = .56, p< .01 [IC95%: .46, .79]) and negative with depression (r = -.48, p< .01 [IC95%: -.37, -.73]). The results suggest that the EAEE presents evidence of validity based on the internal structure, convergent and discriminant, as well as an adequate reliability.

Abstract Introduction: In recent years, satisfaction with life has aroused the interest of gerontological research, thus being one of the most used concepts to measure subjective well-being, in addition to being an indicator of successful aging. Materials and methods: The psychometric properties of the Diener's Satisfaction with Life Scale were assessed in Peruvian elderly individuals. The instrument was applied to 236 elderly from the city of Trujillo (78.4 % female and 21.6 % male), with an average age of 72.8 years old, and their standard deviation = 6.90. In order to obtain convergent and discriminant validity, the tests Single Item of Satisfaction with Life Scale, Brief Resilient Coping Scale and the Geriatric Depression Scale were conducted. Results: Diener's Satisfaction with Life Scale shows a one-dimensional structure (χ2 = 10.960, df = 5, p = .05, χ2/ά/ = 2.192, GFI = .983, CFI = .994, NFI = .988; RMSEA = .071 [ci 90 % .000, .129]; and SRMR = .013), presenting positive correlations with resilience and negative correlations with depression. Moreover, it presents a high reliability index estimated by the method of internal consistency with the Cronbach's Alpha Test (α = .93), Omega coefficient (ω = .93; ci 95 %: .92 -.95) and GLB = .94. Conclusion: For purposes of research -among other-, we recommend the use of the Diener's Satisfaction with Life Scale for Peruvian elderly persons.

OBJECTIVE: To evaluate the effect of presenting a recommendation in a clinical practice guideline using different grading systems to determine to what extent the system used changes the clinician's eventual response to a particular clinical question. DESIGN: Randomised experimental study. SETTING: Clinician offices and academic settings. PARTICIPANTS: Paediatricians and paediatric residents in private and public practice in Mexico. INTERVENTION: Case notes of a child with diarrhoea and a question about clinician preference for using racecadotril. The same evidence was provided in a clinical recommendation but with different presentations according to the following grading systems: NICE (National Institute for Health and Clinical Excellence), SIGN (Scottish Intercollegiate Guideline Network), GRADE (Grading of Recommendations Assessment, Development and Evaluation) and CEBM (Centre for Evidence-Based Medicine, Oxford). MAIN OUTCOME MEASURE: Mean change in direction from baseline response (measured on a 10 cm visual scale and a Likert scale) and among groups. RESULTS: 216 subjects agreed to participate. Most participants changed their decision after reading the clinical recommendations (mean difference 0.7 cm, 95% CI 0.29 to 1.0; p<0.001). By groups, mean change (95% CI) from baseline was 0.04 (-0.68 to 0.77) for NICE, 0.31 (-0.41 to 1.05) for SIGN, 2.18 (1.48 to 2.88) for GRADE and 0.08 (-0.52 to 0.69) for CEBM (p=0.007 between groups). In a final survey, a small difference was noted regarding the clarity of the results presented with the GRADE system. CONCLUSION: The clinician's decision to use a therapy was influenced most by the GRADE system. TRIAL REGISTRATION NUMBER: NCT00940290.

Introducción: El humor tiene un papel importante en la promoción de un envejecimiento exitoso y saludable. Sin embargo, su estudio científico es aún limitado, en parte debido a la ausencia de medidas validadas para su uso en el ámbito latinoamericano. El objetivo del estudio fue traducir al español y examinar las evidencias de fiabilidad y validez basadas en la estructura interna, convergente y discriminante de la versión peruana de la Coping with Humor Scale-5 ítems. Materiales y métodos: Los participantes fueron 236 adultos mayores peruanos (78,4% mujeres y 21,6% hombres) con un promedio de edad de 72,8 años (DE = 6,90). Se realizó un análisis factorial confirmatorio, análisis de correlación (r) y fiabilidad (alfa; alfa de cronbach y omega; omega). Resultados: El modelo unidimensional presentó un ajuste adecuado de los datos (χ2 = 7,72, df = 5, p = 0,17, χ2/df = 1,54, GFI =0,988, CFI =0,996, NFI = 0,988; RMSEA = 0,048 [IC90% 0,000, 0,111]; y SRMR = 0,016). Los índices de fiabilidad son adecuados (alfa= 0,86 [IC95%: 0,82-0,89] y omega = 0,89 [IC95%: 0,87-0,91]). Se observa una correlación positiva entre la puntuación promedio de la CHS-5 y la satisfacción con la vida, y negativa con la depresión. Conclusiones: La CHS-5 presenta excelentes propiedades psicométricas, siendo una medida que brinda interpretaciones válidas y confiables para ser utilizada en adultos mayores peruanos
Introduction: Humour plays an important role in promoting successful and healthy aging. However, its scientific study is still limited, partly due to the absence of validated tools for use in Latin America. The objective of this study was to translate the 5-item Coping with Humor Scale (CHS-5) from English to Spanish and examine the evidence of reliability and validity based on the internal, convergent, and discriminant structure of the Peruvian version of the scale. Materials and method: The participants were 236 elderly Peruvian adults (78.4% A confirmatory factor analysis, analysis of correlation (r), and reliability (alfa, Cronbach's alpha and omega, omega) was performed. Results: The one-dimensional model presented an adequate fit of the data (χ2 = 7.72, df =5, P=.17, χ2 / df = 1.54, GFI = 0.988, CFI = 0.996, NFI = 0.988, RMSEA =0. 048 [95% CI; 0.000-0.111]; and SRMR = 0.016). The reliability indexes were adequate (alfa= 0.86 [95% CI: 0.82-0.89] and omega = 0.89 [95% CI: 0.87-0.91]). A positive correlation was observed between the mean score of CHS-5 and satisfaction with life, and was negative with depression. Conclusions: The CHS-5 has excellent psychometric properties, being a measure that provides valid and reliable interpretations to be used in elderly Peruvians with depression
