Adolescents and youths’ opinions about the factors associated with cannabis use: a qualitative study based on the I-Change model
Background To learn about the experiences and opinions of adolescent non-consumers and regular cannabis users
about cannabis use and the factors that determine its use, using the I-Change explanatory model as a basis.
Methods Qualitative methodology with a content analysis was used. Focus groups were conducted with
adolescents who were non-regular cannabis users (those who had not tried cannabis or had only experimented with
it before) and semi-structured interviews were conducted with adolescent and young adult in recovery who were in a
detoxification program. A deductive analysis of the audio-recorded and transcribed interviews was performed, using
the domains of the I-Change Model as a reference.
Results Personal problems, social problems or family problems can lead to cannabis use. There was a lack
of knowledge and low risk perception about consumption of this drug. There are other factors that influence
consumption, the perception of advantages, such as the feeling of freedom and the influence of the peer group. The
consumption of this substance in girls is changing, becoming more and more equal to that of boys. The family has an
important role to play in preventing drug use.
Conclusion Knowledge of these factors is of vital importance as a prior step to the development of efficient
intervention measures adjusted to the needs identified and the characteristics of the population.

Effects of the ruminal comminution rate and microbial contamination of particles on accuracy of in situ estimates of ruminal degradability and intestinal digestibility of feedstuffs.
Effects of considering the comminution rate -kc- and the correction of microbial contamination -using 15N techniques- of particles in the rumen on estimates of ruminally undegraded fractions and their intestinal digestibility were examined generating composite samples -from rumen-incubated residues- representative of the undegraded feed rumen outflow. The study used sunflower meal -SFM- and Italian ryegrass hay -RGH- and three rumen and duodenum cannulated wethers fed with a 40:60 RGH to concentrate diet -75 g DM/kgBW0.75-. Transit studies up to the duodenum with Yb-SFM and Eu-RGH marked samples showed higher kc values -/h- in SFM than in RGH -0.577 vs. 0.0892, p = 0.034-, whereas similar values occurred for the rumen passage rate -kp-. Estimates of ruminally undegraded and intestinal digestibility of all tested fractions decreased when kc was considered and also applying microbial correction. Thus, microbial uncorrected kp-based proportions of intestinal digested undegraded crude protein overestimated those corrected and kc-kp-based by 39% in SFM -0.146 vs. 0.105- and 761% in RGH -0.373 vs. 0.0433-. Results show that both kc and microbial contamination correction should be considered to obtain accurate in situ estimates in grasses, whereas in protein concentrates not considering kc is an important source of error
Fermented Milks from Small Ruminant: Effect on Metabolism and Immune Status of Mice Fed Mild Caloric Restricted Diet
The purpose of this study was to evaluate the effect of the administration of Fermented Goat´S Milks (FGMs) in mice fed mild caloric restricted diet. The ability of these FGMs to ameliorate immune and metabolic parameters related to mild caloric restriction was studied. We also analyzed if the time (45 or 90 days) of caloric restriction have influence on leptin secretion, IgA+ cells number and phagocytic activity of peritoneal macrophages, and also test the correlation between these parameters. Mice were fed with a mild caloric restricted diet during 45 or 90 days. After these periods of caloric restriction, mice were refed with balanced conventional diet (BCD) plus goat´s milks or BCD plus goat´s milks fermented with Lactobacillus rhamnosus CRL1425 (FGM-Lr) or Lactobacillus casei CRL431 (FGM-Lc). All renutrition diets induced an increase of serum glucose, triglycerides, total proteins and leucocytes cells. A decrease in cholesterol levels was observed after the diets. FGM-Lr induced lower triglycerides values than others diets. All FGMs restore IgA+ cells in intestinal mucosa, and the FGM-Lc group had higher positive cells number than the ad libitum control. Furthermore, phagocytic activity of peritoneal macrophages only increased in mice fed with FGM-Lc. Mild caloric restriction induced a decrease on leptin circulating values at 90 days. The renutrition with FGM-Lr lead to lower leptin levels than mild caloric restriction controls, while FGM-Lc induced higher leptin levels. Positive correlation between serum leptin concentration and immune parameters was observed in all groups under study. We showed that leptin levels could positively predict the immune mucosal competence in mild caloric restricted mice. These results suggest that the FGMs are able to modulate, in different way, serum leptin levels, IgA+ cells number and phagocytic activity. Furthermore, FGM-Lc could be more effective for nutritional treatment in malnutrition status.Fil: Fabersani Marrades, Mario Emanuel. Consejo Nacional de Investigaciones CientÃficas y Técnicas.

Hybrid Fluorescent Mass-Tag Nanotrackers as Universal Reagents for Long-Term Live-Cell Barcoding
Cell barcoding and pooling are essential to reduce technical variability in multiplex technologies. While fluorescent barcoding is common in flow cytometry, current mass-tag barcoding methods are unsuitable for live cells. This study presents fluorescent palladium-based nanotrackers for live cell barcoding, compatible with flow and mass cytometry, enabling long-term drug studies with consistent labeling.This research was supported by funding from the Spanish Ministry of Economy and Competitiveness (BIO2016-80519, PID2019.110987RB.I00); the Health Institute Carlos III (DTS18/00121); the Andalusian Regional Government-FEDER (PT18-TP-4160, B-FQM-475-UGR18, A-FQM-760-UGR20); the Department of Defense (W81XWH-12-1-0591); NCI (1R01CA234553, R21CA231280); the 2019 Cancer Innovation Award, supported by the Stanford Cancer Institute, an NCI-designated Comprehensive Cancer Center; BRCA Foundation and the V Foundation for Cancer Research; a gift from the Gray Foundation; the Department of Urology at Stanford University; NHLBI (P01HL10879709); NIAID (U19AI057229); and a PICI Bedside to Bench grant.

Opinions of Andalusian primary health care professionals about human papillomavirus and its vaccine
Fundamento. El virus del papiloma humano (VPH) es
una de las enfermedades de transmisión sexual más comunes,
pero su tasa de vacunación es de las más bajas
en AndalucÃa. El objetivo de este estudio es conocer las
opiniones de los profesionales sanitarios de Atención
Primaria sobre la prevención en adolescentes de la infección
por el VPH y la administración de su vacuna.
Método. Investigación cualitativa mediante seis grupos
focales con profesionales de centros de Atención Primaria
de Sevilla, Granada y Jaén. Participaron 45 profesionales
sanitarios. Se realizó un análisis de contenido
de tipo semántico con categorización de respuestas en
unidades temáticas.
Resultados. Los profesionales reconocen las dificultades
de llegar a la población adolescente en temas de prevención
de conductas sexuales de riesgo, por falta de
tiempo y poca preocupación de los adolescentes por las
medidas preventivas. Aunque reconocen la sintomatologÃa
de la infección por el VPH, no todos tienen claro si el
varón padece la enfermedad asà como la asociación de la
infección con canceres distintos al de cérvix. Dudan a la
hora de recomendar la vacuna, dejando en manos de los
progenitores la decisión de la vacunación de sus hijas.
Conclusiones. SerÃa recomendable establecer estrategias
que mejoren la información que tienen los profesionales
acerca del VPH, asà como de los beneficios
de la vacuna, para que los trasmitan claramente y con
asertividad a los padres; esto evitarÃa incertidumbre en
los progenitores, mejorarÃa las tasas de vacunación y
disminuirÃa las complicaciones de la infección (cáncer).Background. The human papillomavirus (HPV) is the
most common sexually transmitted disease, but its vaccination
coverage is among the lowest in Andalusia.
The aim of this study is to determine what primary
health care professionals think and find out about the
prevention of HPV infection among adolescents and the
administration of the vaccine
Method. Qualitative study using six focus groups with
professionals from Primary Health Care in Seville, Granada
and Jaen. Fourty-five professionals participated.
An analysis of the semantic content was made, and answers
were categorized in thematic units.
Results. Professionals recognize the difficulties in reaching
the adolescent population concerning prevention
of sexual risk behaviors, due to lack of time and little concern
amongst adolescents about the preventive measures.
Although the professionals recognize the symptoms
of HPV infection, some did not know about the disease
in men as well as the association with other cancers
other than cervical cancer. They hesitate over whether
to recommend the vaccine or not, leaving the decision
to vaccinate their daughters in the hands of the parents.
Conclusion. It would be advisable to establish strategies
that improve the information that the professionals
have about HPV as well as the benefits of the vaccine,
so that they can transmit the benefits clearly and assertively
to the parents. This would avoid parental
uncertainty, improve vaccination rates, and decrease
complications of infection (cancer)
The Use of hCG for Inducing Ovulation in Sheep Estrus Synchronization Impairs Ovulatory Follicle Growth and Fertility
Currently, there is an intense effort to find an alternative hormone to eCG to induce ovulation after estrus synchronization treatments in sheep. One of the proposed alternatives is based on the use of hCG, but the results are controversial since fertility rates are commonly affected. The present study aims to evaluate, therefore, the adequacy of hCG in protocols for the synchronization of estrus
and ovulation. Ovarian follicle dynamics, occurrence of estrus behavior and subsequent ovulation, quality of corpora lutea, and pregnancy rate after controlled natural mating were assessed in two consecutive trials. The findings indicate that the low fertility rates reported for the protocols based on the administration of hCG for inducing ovulation during estrus synchronization in sheep may be
related to a high occurrence of abnormal follicular growth patterns, disturbances, and retardments of ovulation and concomitant formation of follicular cysts in the treated females. These results preclude their practical application to induce ovulation concomitantly to estrous synchronization treatments.Estación Experimental Agropecuaria BarilocheFil: Bruno Galarraga, MarÃa Macarena.

High efficient luminescence in type-II GaAsSb-capped InAs quantum dots upon annealing
The photoluminescence efficiency of GaAsSb-capped InAs/GaAs type II quantum dots (QDs) can be greatly enhanced by rapid thermal annealing while preserving long radiative lifetimes which are ∼20 times larger than in standard GaAs-capped InAs/GaAs QDs. Despite the reduced electron-hole wavefunction overlap, the type-II samples are more efficient than the type-I counterparts in terms of luminescence, showing a great potential for device applications. Strain-driven In-Ga intermixing during annealing is found to modify the QD shape and composition, while As-Sb exchange is inhibited, allowing to keep the type-II structure. Sb is only redistributed within the capping layer giving rise to a more homogeneous composition
Hybrid salivary gland tumor of the upper lip or just an adenoid cystic carcinoma? Case report
A 65 year-old male patient with a one year-duration tumoral growth located in the upper lip was diagnosed on incisional biopsy as epithelial-myoepithelial carcinoma. After wide surgical excision the histopathological analysis revealed the lesion was composed predominantly (>90%) of adenoid cystic carcinoma. In new sections it was found a very small and isolated area of adenoid cystic carcinoma at the bottom of the incisional biopsy. As surgical margins were free of lesion, no adjuvant treatment was given. The occurrence of a transitory ischaemic attack at 36 months of follow-up led to a neurological and MRI evaluation, which disclosed a well-defined 3.5x3 cm lesion suggestive of metastasis, located on the right temporal area. The lesion was surgically removed and a histopathological diagnosis of neurocysticercosis was rendered. After 40 months of follow-up there is no evidence of recurrence. Conclusion: True hybrid tumors of salivary glands are rare and treatment in each case should be done according to the component with the higher aggressiveness. However, the occurrence of epithelial-myoepithelial carcinoma areas within an adenoid cystic carcinoma seems to be a frequent finding, and because both lesions share a common origin, some authors consider that this may not be a true hybrid neoplasm but a variant of the latte
