Phenolic compounds in extra virgin olive oil stimulate human osteoblastic cell proliferation

In this study, we aimed to clarify the effects of phenolic compounds and extracts from different extra virgin olive oil (EVOO) varieties obtained from fruits of different ripening stages on osteoblast cells (MG-63) proliferation. Cell proliferation was increased by hydroxytyrosol, luteolin, apigenin, p-coumaric, caffeic, and ferulic acids by approximately 11–16%, as compared with controls that were treated with one vehicle alone, while (+)-pinoresinol, oleuropein, sinapic, vanillic acid and derivative (vanillin) did not affect cell proliferation. All phenolic extracts stimulated MG-63 cell growth, and they induced higher cell proliferation rates than individual compounds. The most effective EVOO phenolic extracts were those obtained from the Picual variety, as they significantly increased cell proliferation by 18–22%. Conversely, Arbequina phenolic extracts increased cell proliferation by 9–13%. A decline in osteoblast proliferation was observed in oils obtained from olive fruits collected at the end of the harvest period, as their total phenolic content decreases at this late stage. Further research on the signaling pathways of olive oil phenolic compounds involved in the processes and their metabolism should be carried out to develop new interventions and adjuvant therapies using EVOO for bone health (i.e.osteoporosis) in adulthood and the elderly

Resiliencia, género y rendimiento académico en jóvenes universitarios del Estado de Morelos

Resilience has been widely studiedin the field of psichology to define those who achieve success despite adeversecircumstances. Thus, a study is carried out whose objective was to evaluate the correlation between resilience and academic performance (RA), according to gender in university students, for which an analytical cross-sectional design was applied, with the participation of 51 undergraduate students in nutrition (18 men and 33 women; from 21 to 32 years old) from the Universidad Autónoma del Estado de Morelos (UAEM). To evaluate the variables, a sociodemographic questionare was used, the Asilient Anomie and Nomic Resilience Inventory (IAAR); and to determine the Academic Performance the grade point average for the current semester was requested. Results show that there is a positive relationship between resilience and Academic Performance, as well as in the results of resilience and gender, finally it is evidenced that male students have higher levels of resilience than women and that academic performance is related to the resilience.La resiliencia ha sido estudiada ampliamente en el campo de la psicología para definir aquellas personas que alcanzan el éxito pese a las circunstancias adversas. En este sentido, se realiza un estudio cuyo objetivo fue, evaluar la correlación entre resiliencia, rendimiento académico (RA), según el género en jóvenes universitarios, para lo cual se aplicó un diseño transversal analítico en donde participaron 51 estudiantes de la Licenciatura en Nutrición de la Universidad Autónoma del Estado de Morelos (UAEM) (18 hombres y 33 mujeres; de 21 a 32 años). Para evaluar las variables, se utilizó un cuestionario sociodemográfico, el inventario de anomia asiliente y resiliencia nomica (IAAR); y para determinar el RA se solicitó el promedio de calificaciones del semestre en curso. Los resultados evidencian que existe relación positiva entre resiliencia y RA, así como en los resultados de resiliencia y género, finalmente se evidencia que, los estudiantes del sexo masculino poseen niveles más altos de resiliencia que las mujeres y que el rendimiento académico se ve relacionado con la resiliencia

Evaluación de los parámetros antropométricos en una muestra nacional de adultos mayores mexicanos

The purpose of this study was to describe anthropometric parameters in a population of Mexican older adults (OA). 516 OA (277 women, 239 men) aged ≥ 65 years were interviewed. Anthropometry and a sociodemographic data questionnaire were performed. Means and standard deviations, prevalence (%) and confidence intervals are reported in the results. SPSS v20.0 was used in the statistical analysis. The combined prevalence of overweight and obesity in our population was 77%. The mean WHR values obtained were (0.97 in men and 0.89 in women). Finally, the percentage of fat in men was 30.6% and in women it was 39.8%. The results of this investigation showed significant differences between men and women in most of the anthropometric measures and nutrition indicators. The prevalence of overweight and obesity reported in the Mexican elderly population was higher than that reported in other studies, which shows an important public health problem in Mexican older adults. More studies are needed at the national level on nutritional parameters in the elderly in order to detect cardiovascular risk factors in a timely manner.El propósito de este estudio fue describir los parámetros antropométricos en una población de adultos mayores (AM) mexicanos. Se entrevistó a 516 AM (277 mujeres, 239 hombres) con ≥ 65 años de edad. Se realizó antropometría, y un cuestionario de datos sociodemográficos. En los resultados se reportan medias y desviaciones estándar, prevalencias (%) e intervalos de confianza. En el análisis estadístico se utilizó el SPSS v20.0. La prevalencia conjunta de sobrepeso y obesidad en nuestra población fue de 77%. Los valores medios de Indice Cintura-Cadera obtenidos fueron (0.97 hombres y 0.89 en mujeres). Por último, el porcentaje de grasa en hombres fue 30.6 % y en mujeres fue 39.8 %. Los resultados de esta investigación arrojaron diferencias significativas entre hombres y mujeres en la mayoría de las medidas antropométricas e indicadores de nutrición. La prevalencia de sobrepeso y obesidad reportada en la población mexicana de edad avanzada fue más alta que lo reportado en otros estudios, lo que muestra un importante problema de salud pública en los en adultos mayores mexicanos. Se requieren más estudios a nivel nacional sobre los parámetros nutricionales en AM con el fin de detectar de forma oportuna factores de riesgo cardiovascular.Actividad Física y Deport

HTLV-1 infection in solid organ transplant donors and recipients in Spain

HTLV-1 infection is a neglected disease, despite infecting 10-15 million people worldwide and severe illnesses develop in 10% of carriers lifelong. Acknowledging a greater risk for developing HTLV-1 associated illnesses due to immunosuppression, screening is being widely considered in the transplantation setting. Herein, we report the experience with universal HTLV testing of donors and recipients of solid organ transplants in a survey conducted in Spain. All hospitals belonging to the Spanish HTLV network were invited to participate in the study. Briefly, HTLV antibody screening was performed retrospectively in all specimens collected from solid organ donors and recipients attended since the year 2008. A total of 5751 individuals were tested for HTLV antibodies at 8 sites. Donors represented 2312 (42.2%), of whom 17 (0.3%) were living kidney donors. The remaining 3439 (59.8%) were recipients. Spaniards represented nearly 80%. Overall, 9 individuals (0.16%) were initially reactive for HTLV antibodies. Six were donors and 3 were recipients. Using confirmatory tests, HTLV-1 could be confirmed in only two donors, one Spaniard and another from Colombia. Both kidneys of the Spaniard were inadvertently transplanted. Subacute myelopathy developed within 1 year in one recipient. The second recipient seroconverted for HTLV-1 but the kidney had to be removed soon due to rejection. Immunosuppression was stopped and 3 years later the patient remains in dialysis but otherwise asymptomatic. The rate of HTLV-1 is low but not negligible in donors/recipients of solid organ transplants in Spain. Universal HTLV screening should be recommended in all donor and recipients of solid organ transplantation in Spain. Evidence is overwhelming for very high virus transmission and increased risk along with the rapid development of subacute myelopathy

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

Role of age and comorbidities in mortality of patients with infective endocarditis

[Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. [Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. [Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. [Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group
