RESUMEN
Palm weevils, Rhynchophorus spp., are destructive pests of native, ornamental, and agricultural palm species. Of the 10 recognized species, two of the most injurious species, Rhynchophorus ferrugineus and Rhynchophorus palmarum, both of which have spread beyond their native range, are the best studied. Due to its greater global spread and damage to edible date industries in the Middle East, R. ferrugineus has received more research interest. Integrated pest management programs utilize traps baited with aggregation pheromone, removal of infested palms, and insecticides. However, weevil control is costly, development of resistance to insecticides is problematic, and program efficacy can be impaired because early detection of infestations is difficult. The genome of R. ferrugineus has been sequenced, and omics research is providing insight into pheromone communication and changes in volatile and metabolism profiles of weevil-infested palms. We outline how such developments could lead to new control strategies and early detection tools.

PURPOSE: To describe the outcome of the patients diagnosed of sagging/heavy eye associated to myopia, that were operated on with the supra-equatorial displacement with LR myopexy. METHODS: A retrospective study of 9 cases between 2017-2023. The following data were analyzed: horizontal and vertical deviation, diplopia, amblyopia, ductions, ocular torsion, sensorial test, macular pathology, and the orbital magnetic resonance. Treatment was considered Successful if the diplopia was improved or eliminated and a final vertical deviation (VD) ≤5 prism diopters (PD). RESULTS: The mean age (SD) was: 62.11 (4.6) years (100% women). A total of 88.88% presented diplopia. The mean preoperative hypotropia was: 11.33 PD (SD 3.16), and the mean final VD 3.44 PD (SD 3.05). After surgery, the hypotropia was overcorrected in one case, under corrected in 5, and orthophoria was achieved in another three. The technique was associated with surgery of another rectus muscle in 4 subjects. The mean follow-up time after surgery was 34 months (SD 34.62). Six of the 9 patients improved with a vertical deviation ≤5 PD. In 3 patients, the diplopia was eliminated, while in 5 it remained intermittent (three with macular pathology). CONCLUSION: Supra-equatorial displacement with LR myopexy for treatment of myopic sagging/heavy eye, is a therapeutic option if hypotropia is less than 12 PD or the Yokoyama technique is not indicated. A good result was obtained in most cases, although diplopia could only be totally suppressed in three, and another five remained intermittent.

La composición química del aceite de oliva extra virgen (AOEV) se compone principalmente de triglicéridos, ácidos grasos insaturados como ácido oleico, ácido linoleico y el α-linolénico. También se destacan compuestos fenólicos de tres clases químicas: simples, secoiridoides y lignanos. En la presente revisión se analizó el consumo del AOEV en enfermedades crónicas, ciertos tipos de cáncer y en enfermedades neurodegenerativas. La evidencia muestra que el consumo de entre 8 y 40 g de AOEV diario tiene efectos protectores en enfermedades cardiovasculares, puede evitar la aparición de diabetes tipo 2 y aumentar los niveles de colesterol HDL. Respecto al cáncer, entre los efectos evaluados se destacan los encontrados a partir de los compuestos fenólicos hidroxitirosol (HT) y oleocantal, los que han demostrado un efecto protector en algunos tipos de cáncer como cáncer de piel y de mama. En las enfermedades neurodegenerativas, se observó que el consumo diario de 50 g de AOEV, tiene un efecto inhibidor en la degeneración neuronal atribuido a sus compuestos fenólicos como oleuropeina e HT. Investigaciones a futuro debieran enfocarse en determinar los efectos a largo plazo del consumo de AOEV en las diferentes enfermedades analizadas, para así poder ir estableciendo la "dosis" de AOEV que permita obtener resultados protectores sobre la salud. Además de explorar los efectos de las diferentes variedades de aceitunas (con sus componentes bioactivos particulares) con el fin de establecer los efectos en la salud y enfermedad asociados a variedades específicas.
The chemical composition of extra virgin olive oil (EVOO) is mainly composed of triglycerides, unsaturated fatty acids such as oleic acid, linoleic acid, and α-linolenic acid. Phenolic compounds of three chemical classes are also relevant, such as simple, secoiridoids, and lignans. Here, we review the association between EVOO consumption and chronic diseases, certain types of cancer, and neurodegenerative diseases. Evidence shows that consuming between 8 and 40 g of EVOO / day has protective effects on cardiovascular diseases, can prevent the onset of type 2 diabetes, and increases HDL cholesterol levels. Regarding cancer, phenolic compounds hydroxytyrosol (HT) and oleocanthal have protective effects on some types of cancer, such as skin and breast cancer. Regarding neurodegenerative diseases, daily consumption of phenolic compounds such as oleuperin and hydroxytyrosol and 50 g of EVOO has an inhibitory effect on neuronal degeneration and a protective effect on neuroprotective capacity. Future research should focus on determining the long-term impact of EVOO consumption on different diseases to establish the "dose" of EVOO that will allow health-protective results. It is also necessary to establish the effects of the specific olives (with their particular bioactive components) to establish the different impacts on health and disease associated with olives varieties.
RESUMEN
PURPOSE: To evaluate the outcomes of REPA and establish if any differences in complications and evolution are present between males and females. METHODS: A retrospective study including consecutive patients operated by REPA approach between November 2017 and April 2019 was conducted. Demographic data, operative times, postoperative complications, and hospital stay were analyzed. The EuraHS-QoL score was used to assess postoperative pain, daily activity constraints, and aesthetic discomfort. The results were compared between sexes. Statistical analysis was performed using SPSS 19. RESULTS: Fifty-four patients were included and 53.7% were male. Patients had a mean age of 50.7 years and a mean BMI of 28.7. The average RAD (Rectus Abdominis Diastasis) size was 2.6 cm (range of 2-5 cm). Seroma was significantly more frequent in males, with an incidence of 55.2 and 24% for females (p = 0.02). Three cases required reintervention (5.5% of total cases), which corresponded to a cystic seroma, an abdominal wall hematoma, and a hernia recurrence. The three cases were males and a p value of 0.04 was obtained when comparing reintervention rates between males and females. No cases of surgical wound infection nor cutaneous necrosis were recorded. No conversions were needed. The mean postoperative pain was 2.25, the mean daily activity constraints score was 2.63, and the degree of aesthetic discomfort was 1.23 with no significant differences between groups. CONCLUSION: The correction of small midline defect associated with minor RAD using REPA seems feasible and reproducible. REPA had achieved good results in females, but in males, the outcomes were poorer.

The use of DNA barcoding has revolutionised biodiversity science, but its application depends on the existence of comprehensive and reliable reference libraries. For many poorly known taxa, such reference sequences are missing even at higher-level taxonomic scales. We harvested the collections of the Smithsonian's National Museum of Natural History (USNM) to generate DNA barcoding sequences for genera of terrestrial arthropods previously not recorded in one or more major public sequence databases. Our workflow used a mix of Sanger and Next-Generation Sequencing (NGS) approaches to maximise sequence recovery while ensuring affordable cost. In total, COI sequences were obtained for 5,686 specimens belonging to 3,737 determined species in 3,886 genera and 205 families distributed in 137 countries. Success rates varied widely according to collection data and focal taxon. NGS helped recover sequences of specimens that failed a previous run of Sanger sequencing. Success rates and the optimal balance between Sanger and NGS are the most important drivers to maximise output and minimise cost in future projects. The corresponding sequence and taxonomic data can be accessed through the Barcode of Life Data System, GenBank, the Global Biodiversity Information Facility, the Global Genome Biodiversity Network Data Portal and the NMNH data portal.
RESUMEN
The objective was to compare clinical protection [evaluated through health scoring, endoscopy score of the upper respiratory tract (URT-ES), leukocyte count, viremia, and virus shedding in nasal secretions] following Bovine viral diarrhea virus 2 (BVDV2) and Bovine herpes virus 1 (BHV1) challenge among calves submitted to modified-live virus (MLV) booster vaccination (either intranasal or subcutaneous) concurrent with injectable trace minerals (ITM) or saline. Forty-eight dairy calves received an MLV intranasal (IN) vaccine containing BHV1, BRSV, and BPI3V and subcutaneous (SC) ITM (Se, Cu, Zn & Mn; ITM, n = 24) or saline (SAL, n = 24). Ten weeks later, calves received a second dose of ITM, or saline, according to previous groups and were randomly assigned to receive the same IN vaccine [ITM-IN (n = 12), SAL-IN (n = 12)] or a SC MLV vaccine containing BHV1, BRSV, BPI3V, BVDV1 & 2 [ITM-SC (n = 12), SAL-SC (n = 12)]. Additionally, 12 calves did not receive vaccine or treatment and served as a control group (UNVAC, n = 12). Forty-nine days after booster, calves were challenged with BVDV2; and seven days later with BHV1. Health scores indicated disease in UNVAC on days 6, 10 and 12 compared to the vaccinated groups. Unvaccinated calves had the highest URT-ES after BHV1 challenge. Calves that received SC booster had lower URT-ES after BHV1 challenge than UNVAC calves. Calves in ITM-IN had significantly lower URT-ES after BHV1 infection than SAL-IN and UNVAC calves. In conclusion, IN or SC MLV vaccination was similarly effective in protecting calves from BVDV2 + BHV1 challenges (reducing clinical and endoscopy scores, preventing leukopenia, and viremia), compared to unvaccinated calves. Endoscopic evaluation of the URT allowed visualization of the inflammation and damage at multiple depths in the URT caused by a serial BVDV2 + BHV1 challenge. Calves that received SC vaccination had significantly lower URT-ES after BHV1 challenge than the UNVAC calves. Administration of ITM concurrent with IN vaccination was associated with reduced URT inflammation after BVDV2 + BHV1 challenge.

This paper describes two new helical arrays of magnetic coils recently installed inside the TJ-II vacuum vessel. Their main objective is the precise measurement of the spatial periodicity of the magnetohydrodynamic perturbations usually found in the TJ-II plasmas. Given the high probability of coil failures due to the harsh plasma environment and in view of the extremely difficult access to the TJ-II vessel interior for maintenance, the coil system has been divided in two quasi-identical helical arrays. Both arrays consist of 32 triaxial sensors measuring orthogonal components of the local magnetic field along an ideal helical path whose trajectory runs close to the plasma edge. A description of the main characteristics of coils and arrays as well as their nominal positioning along an ideal helical path, inside the vessel, is given. A precise experimental determination of the real spatial orientation of the coils is performed by comparing the signals measured in current ramp-up and ramp-down experiments with calculations based on a filamentary model for the TJ-II magnetic coils. After this fine calibration procedure, it is possible to analyze the dependence of the amplitude of the measured magnetic field and its fluctuations as a function of the coil distance to the last closed flux surface. The study of the phase evolution of the parallel and perpendicular oscillatory components is also enabled. Finally, two examples of mode number determination are shown. One corresponds to a low frequency mode appearing in pure electron cyclotron resonance heating plasma, and the other one shows several modes observed during combined injection of both co and counter neutral beams and identified as shear Alfvén waves.
RESUMEN
Objetivo: Describir la prevalencia del parto adolescente por cohorte a través de los años y su relación con factores sociodemográficos, en Panamá. Metodología: A partir de un análisis secundario de la "Encuesta nacional de salud sexual y reproductiva 2014-2015" de Panamá, utilizando cohortes por año de nacimiento (1966-1975, 1976-1985, 1986-1995 y 1996-2000), la relación enunciada se analizó mediante regresión logística. Se incluyeron 4795 adultas (20-49 años) y 821 adolescentes (15-19 años). Resultados: Se encontró un aumento en la prevalencia del parto adolescente entre cohortes, donde la prevalencia fue de 30,9 % en la cohorte mayor (1966-1975) y de 51,5 % en la cohorte de 1986-1995. En todas las cohortes, el parto adolescente estuvo asociado a la ruralidad (1966-1975, 42,3 % rural no indígena; 1976-1985, 56,6 % rural indígena; 1986-1995, 65,4 % rural no indígena y 58,2 % rural indígena). En todas las cohortes, el parto adolescente se relacionó con menor bienestar, encontrándose una prevalencia mayor que el 40 % en el quintil menor de riqueza en todas las cohortes. El parto adolescente se asoció a tener 4 o más hijos en las cohortes mayores (1966-1975 y 1976-1985), con prevalencias mayores que el 63 %. Conclusiones: La prevalencia del parto en adolescente en Panamá se ha mantenido en crecimiento. Las poblaciones rurales y de menor bienestar se han mantenido con mayor prevalencia de parto adolescente, indicando dónde enfocar las intervenciones preventivas.
Objective: To describe the prevalence of adolescent childbirth by cohort over time and its relationship with sociodemographic factors in Panama. Methodology: The analysis was conducted through logistic regression, based on a secondary analysis of the Panama "Encuesta nacional de salud sexual y reproductiva 2014- 2015" (2014-2015 National Survey on Sexual and Reproductive Health), using cohorts by year of birth (1966-1975, 1976-1985, 1986-1995, and 1996-2000). A total of 4795 adult women (20-49 years old) and 821 adolescent girls (15-19 years old) were included. Results: We found an increased prevalence of adolescent childbirth between cohorts, where prevalence was 30.9% in the older cohort (1966-1975) and 51.5% in the 1986- 1995 cohort. In all cohorts, adolescent childbirth was associated with rurality (1966-1975, 42.3% rural non Indigenous; 1976- 1985, 56.6% rural Indigenous; 1986-1995, 65.4% rural non Indigenous, and 58.2% rural Indigenous). Adolescent childbirth was also associated with lower well-being; across all cohorts, there was a prevalence of over 40% in the lowest wealth quintile. Adolescent childbirth was associated with having 4 or more children in the older cohorts (1966-1975 and 1976-1985), with a prevalence of over 63%. Conclusions: The prevalence of adolescent childbirth in Panama has continued to increase. Rural and lower well-being populations have continued to exhibit a higher prevalence of adolescent childbirth, which signals where to focus preventive interventions.

As populações rurais e com menor bem-estar mantêm a maior prevalência do parto adolescente, indicando onde enfocar as intervenções preventivas.
RESUMEN
INTRODUCTION AND OBJECTIVES: Although much has been published on the effect of the pandemic on trauma emergencies, it has not been analysed whether the incidence of infection or different organisation of available resources according to the Spanish region were influential factors. We present a multicenter study of three tertiary hospitals in three Spanish cities with different characteristics to study how these factors influenced paediatric trauma emergencies during the first wave of the pandemic. MATERIAL AND METHODS: We present a retrospective cohort study that compares and analyzes paediatric trauma emergencies in three different hospitals during the period of the first wave of the COVID-19 pandemic and we compare them with the same period of the previous year, analyzing the number of emergencies, the severity of the pathology, the average age of the patients, the days of admission and the waiting time of the cases that required surgical treatment. RESULTS: A total of 6474 paediatric trauma emergency episodes have been analysed. There was a drastic reduction in activity in the three hospitals, but in different amounts: 83.5% in the hospital located in Madrid, 75% in the hospital located in Valencia and 65.9% in the one located in Palma, Majorca. The emergencies attended were more serious in 2020 compared to 2019. The average age of patients treated during the pandemic was lower compared to the previous year. There were no differences in the days of admission, but there were differences in the delay in surgery for surgical fractures. CONCLUSIONS: The impact of the first wave of the COVID-19 pandemic and the decreed confinement had a different impact on paediatric trauma emergencies in the different hospitals according to the incidence of infection and the measures adopted in the different regions. In all cases there was a significant reduction in activity, a greater proportion of medium and severe pathologies were attended to, the average age of the patients attended was lower and a delay was observed in surgeries performed in the emergency room, probably due to the need to request a PCR test to detect a COVID-19 infection.

RESUMEN
BACKGROUND: Estimation of survival requires follow-up of patients from diagnosis until death ensuring complete and good quality data. Many population-based cancer registries in low- and middle-income countries have difficulties linking registry data with regional or national vital statistics, increasing the chances of cases lost to follow-up. The impact of lost to follow-up cases on survival estimates from small population-based cancer registries (<500 cases) has been understudied, and bias could be larger than in larger registries. METHODS: We simulated scenarios based on idealized real data from three population-based cancer registries to assess the impact of loss to follow-up on 1-5-year overall and net survival for stomach, colon, and thyroid cancers-cancer types with very different prognosis. Multiple scenarios with varying of lost to follow-up proportions (1-20%) and sample sizes of (100-500 cases) were carried out. We investigated the impact of excluding versus censoring lost to follow-up cases; punctual and bootstrap confidence intervals for the average bias are presented. RESULTS: Censoring of lost to follow-up cases lead to overestimation of the overall survival, this effect was strongest for cancers with a poor prognosis and increased with follow-up time and higher proportion of lost to follow-up cases; these effects were slightly larger for net survival than overall survival. Excluding cases lost to follow-up did not generate a bias on survival estimates on average, but in individual cases, there were under- and overestimating survival. For gastric, colon, and thyroid cancer, relative bias on 5-year cancer survival with 1% of lost to follow-up varied between 6% and 125%, 2% and 40%, and 0.1% and 1.0%, respectively. CONCLUSION: Estimation of cancer survival from small population-based registries must be interpreted with caution: even small proportions of censoring, or excluding lost to follow-up cases can inflate survival, making it hard to interpret comparison across regions or countries.
