To accurately identify the species that make up the assemblage of the family Cichlidae in the Mexican state of Chiapas, we first updated the total species account (36 species) for the state and then created an identification key. For the distribution maps, the geographic records were projected using a geographic information system considering the layers of the two largest basins in the state (Grijalva and Usumacinta) and the Chiapas coast basin. The dichotomous key includes meristic, morphometric and coloration patterns that facilitate species identification present in the state. Rheoheros coeruleus (Stawikowski and Werner 1987) and Vieja breidohri Werner and Stawikowski 1987 are included in a key for the first time. The distributions of Paraneetroplus gibbiceps Steindachner 1864a, Rheoheros coeruleus, and Vieja zonata Meek 1905 in the state are mapped for the first time, and the range of 16 species was expanded. By updating and creating tools of great taxonomic use, we contribute to the study of this complex family with high morphological diversity.

Different gene expression between male and female bovine embryos leads to metabolic differences.We used UHPLC-MS/MS to identify sex metabolite biomarkers in embryo culture medium (CM).Embryos were produced in vitro under highly variable conditions, i.e., fertilized with 7 bulls, two breeds, and cultured with BSA or BSA + serum until Day-6. On Day-6, embryos were cultured individually for 24 h. CM of Day-7 embryos (86 female and 81 male) was collected, and Day-6 and Day-7 embryonic stages recorded.A study by sample subsets with fixed factors (culture, bull breed, and Day-6 and Day-7 stages) tentatively identified 31 differentially accumulated metabolites through 182 subsets. Day-6 and Day-7 stage together affected 13 and 11 metabolites respectively, while 19 metabolites were affected by one or another stage and/or day. Culture supplements and individual bull changed 19 and 15 metabolites, respectively. Single bull exerted the highest influence (20 metabolites with the significantly highest p values). Lipid (93 subsets; 11 metabolites) and amino acid (55 subsets; 13 metabolites) were the most relevant classes for sex identification.Single biomarker led to inefficient sex diagnosis, while metabolite combinations accurately identified sex. Our study is a first in non-invasive sex identification in cattle by overcoming factors that induce metabolic variation.

Resumen Objetivo: Describir los conocimientos, las actitudes y las prácticas acerca de la toxoplasmosis en dos comunas de Armenia, Quindío, con alta prevalencia de la infección. Metodología: Estudio descriptivo con población de dos comunas de Armenia, Quindío. Se aplicó un cuestionario autodiligenciado tipo conocimientos, actitudes y prácticas. Esta herramienta incluyó elementos sobre el parásito Toxoplasma gondii, sus vías de transmisión, aspectos clínicos, diagnósticos y de tratamiento generales, así como prácticas para evitar la infección. El instrumento se aplicó antes y después de una intervención educativa. Se describieron las frecuencias en el número de respuestas correctas antes y después de la intervención para cada comuna. Resultados: Participaron 27 personas, con una media de edad de 57 años. El 59 % fueron mujeres. El 48% había completado la educación media y el 40,7 % la primaria.

Abstract Objective: To describe knowledge, attitudes and practices related to toxoplasmosis in two districts of high prevalence in Armenia, Quindío. Methodology: descriptive study; the population of two districts of Armenia, Quindío were engaged. A self-administered questionnaire regarding knowledge, attitudes, and practices was applied. This tool included elements related to Toxoplasma gondii, its transmission pathways, general clinical, diagnostic and treatment aspects, as well as practices to prevent infection. The instrument was applied before and after an educational intervention. Frequencies were described as the number of correct answers before and after the intervention for each district. Results: 27 people participated, with an average age of 57 years. 59 % were women; 48 % had completed high school and 40.7 % had completed elementary school. Before the intervention, the knowledge of the causal agent was 22 %, while after the intervention, it was 92.3 % in district 1 and 81.8 % in district 6. After the intervention, about 90 % of participants recognized the retina as the main compromised structure and all participants recognized the consumption of boiled water as a protective factor. Conclusion: The knowledge regarding toxoplasmosis in the two districts was limited. After the educational intervention, there was an increase in the percentage of correct answers in most of the questions. New educational and public health interventions are recommended to assess the long-term effects of these interventions.

Due to advances in retroviral treatment, human immunodeficiency virus (HIV)-related disease may become chronic and the patient survival has substantially increased. Osteoarticular disease in those patients include multifocal osteonecrosis and its complications. Pain and functional limitation may be due to these complications, frequently underdiagnosed, including pathological fractures. Its prompt management may require a different approach than osteosynthesis. We present a long-term chronic HIV patient with severe pain and limitation. A tibial plateau pathological fracture associated to multifocal osteonecrosis was identified and treated with osteonecrosis debridement and total knee arthroplasty (TKA). Acute periprosthetic joint infection developed and required debridement, antibiotic and implant retention. The contralateral knee, also with multiple osteonecrosis foci, was managed with early TKA. We highlight the importance of timely surgical reconstruction to avoid serious limitation and complications.

Despite different criteria to diagnose a prosthetic joint infection (PJI), aetiological diagnosis of the causing microorganism remains essential to guide treatment. Molecular-biology-based PJI diagnosis is progressing (faster, higher specificity) in different techniques, from the experimental laboratory into clinical use. Multiplex polymerase chain reaction techniques (custom-made or commercial) provide satisfactory results in clinical series of cases, with specificity close to 100% and sensitivity over 70–80%. Next-generation metagenomics may increase sensitivity while maintaining high specificity. Molecular biology techniques may represent, in the next five years, a significant transformation of the currently available microbiological diagnosis in PJI.

Background & aims: Epidemiological data on iron status and cardiovascular disease (CVD) are still controversial. The aim of this study was to determine whether low serum iron (SI) levels are associated with an increased odds of first CVD event in a population at high cardiovascular risk. Methods: Case-control study design nested within the "PREvención con DIeta MEDiterránea" (PREDIMED) trial. A total of 207 participants diagnosed with CVD (myocardial infarction, stroke or cardiovascular death) during follow-up period (2003-2010) were matched by sex, age and intervention group to 436 controls by incidence density sampling. Median time between serum sample collection and subsequent CVD event occurrence was 0.94 years. Inductively coupled plasma mass spectrometry analysis was used to determine SI levels. In-person interviews, medical record reviews, and validated questionnaires were used to assess covariates. Multivariable-adjusted odds ratios (ORs) of CVD were calculated with conditional logistic regression. Results: Mean SI levels were higher in men than in women (1224.0 μg/L vs. 1093.8 μg/L; p < 0.001). Among women, but not in men, the mean SI concentration was lower in cases than in controls (1008.5 μg/L vs. 1132.9 μg/L; p = 0.030). There was a gradual decrease in the multivariable-adjusted ORs of CVD with increasing SI levels (highest vs. lowest quartile: OR = 0.55, 95% CI: 0.32-0.93; ptrend = 0.020). This inverse relationship was more pronounced among women (highest vs. lowest quartile: OR = 0.15, 95% CI: 0.03-0.69; ptrend = 0.011). Conclusions: The present findings are consistent with previously reported inverse associations between SI and CVD. SI levels as an independent marker of short-term cardiovascular risk may be useful for risk assessment in older populations.

Focal therapy (FT) ablates areas of prostate cancer rather than treating the whole gland. We compared oncological outcomes of FT to radical prostatectomy (RP). Using prospective multicentre databases of 761 FT and 572 RP cases (November/2005-September/2018), patients with PSA

El objetivo del artículo es mostrar cómo una versión modificada del método de Sgreccia, con las categorías de adaptabilidad y calidad de vida, resulta de utilidad para formular y pensar los problemas de las personas ancianas y adultos mayores en la emergencia del Covid-19. Para lograr lo anterior se retoman los pasos del método bioético: hecho biomédico, valores antropológicos involucrados y respuesta al problema con las categorías de calidad de vida y adaptabilidad. Se analizan los datos empíricos relacionados con la vejez y el Covid-19, mostrando la vulnerabilidad de este grupo frente a la pandemia. Posteriormente, se derivan los deberes éticos que se generan en torno a las personas mayores y ancianas, establecidas por la reflexión y por medio de las categorías. En conclusión, se busca así que las categorías señaladas nos llevan a reconocer la solidaridad y sociabilidad como el eje del equilibrio entre responsabilidad y deber ante los ancianos.

Mucho se ha venido hablando respecto a la profundización que requiere el canal de Buenaventura. No obstante, pareciera que la solución aún no se vislumbra claramente en un corto plazo. Entretanto el puerto sigue perdiendo carga y competitividad, lo cual ha sido evidente en una disminución constante desde el 2017 según las cifras de arribos internacionales que se mantenían alrededor de los 1400, y el pasado 2020 registraron 1075. ¿Pero, cuáles son las bases para establecer las mejoras al canal de navegación de Buenaventura desde una perspectiva netamente técnica?

The problem of model recovering in the presence of impulse noise on the data is considered for the magnetotelluric (MT) inverse problem. The application of total variation regularization along with L1-norm penalized data fitting (TVL1) is the usual approach for the impulse noise treatment in image recovery. This combination works poorly when a high level of impulse noise is present on the data. A nonconvex operator named smoothly clipped absolute deviation (TVSCAD) was recently applied to the image recovery problem. This operator is solved using a sequence of TVL1 equivalent problems, providing a significant improvement over TVL1. In practice, TVSCAD requires the selection of several parameters, a task that can be very difficult to attain. A more simple approach to the presence of impulse noise in data is presented here. A nonconvex function is also considered in the data fitness operator, along with the total variation regularization operator. The nonconvex operator is solved by following a half-quadratic procedure of minimization. Results are presented for synthetic and also for field data, assessing the proposed algorithm’s capacity in model recovering under the influence of impulse noise on data for the MT problem.

A novel strategy for the synthesis of policyclic trifluoromethyl arenes has been devised. It involves a DBU-promoted tandem cycloaromatization reaction of dicyanoalkenes and fluorinated conjugated sulfinyl imines. This unprecedented transformation is a metal-free and air-tolerant process that takes place from readily available starting materials under mild reaction conditions.

Background Genetic, observational, and clinical intervention studies indicate that circulating levels of triglycerides and cholesterol transported in triglyceride-rich lipoproteins (remnant cholesterol) can predict cardiovascular events. Objectives This study evaluated the association of triglycerides and remnant cholesterol (remnant-C) with major cardiovascular events in a cohort of older individuals at high cardiovascular risk. Methods This study determined the baseline lipid profile and searched for major adverse cardiovascular events (MACEs) in the high-risk primary prevention PREDIMED (Prevencion con Dieta Mediterranea) trial population (mean age: 67 years; body mass index: 30 kg/m2; 43% men; 48% with diabetes) after a median follow-up of 4.8 years. Unadjusted and adjusted Cox proportional hazard models were used to assess the association between lipid concentrations (either as continuous or categorical variables) and incident MACEs (N = 6,901; n cases = 263). Results In multivariable-adjusted analyses, triglycerides (hazard ratio [HR]: 1.04; 95% confidence interval [CI]: 1.02 to 1.06, per 10 mg/dl [0.11 mmol/l]; p 150 mg/dl [1.69 mmol/l] and HDL-C Conclusions In overweight or obese subjects at high cardiovascular risk, levels of triglycerides and remnant-C, but not LDL-C, were associated with cardiovascular outcomes independent of other risk factors.

Infertility is a growing worldwide public health problem, and stress is a main factor exerting detrimental effects on female reproduction. However, knowledge regarding the neuroendocrine changes caused by chronic stress in females is limited. Therefore, this study assessed the effects of stress on hormones that control female reproduction during the proestrus and diestrus stages of the estrous cycle, as well as its effects on fertility. Adult females were assigned to either a control or a stress group. Stress consisted of exposure, for 15 min, to cold-water immersion daily for 30 days. Estrous cyclicity, female sexual behavior, as well as hypothalamic kisspeptin, gonadotropin releasing hormone (GnRH) content, serum luteinizing hormone (LH), estradiol (E2), progesterone (P4), corticosterone (CORT) and fertility were assessed after chronic stress. The results show that chronically stressed females exhibited disrupted estrous cyclicity, decreased receptivity, low pregnancy rates and lower numbers of fetuses. The content of Kisspeptin and GnRH in the Anteroventral Periventricular/medial Preoptic Area decreased during proestrus, while Kisspeptin increased in the Arcuate nucleus in proestrus and diestrus. Serum LH decreased only during proestrus, whereas E2 and P4 concentrations decreased during proestrus and diestrus, with a concomitant increase in CORT levels in both stages. As a whole, these results indicate that chronic stress decreases Kisspeptin content in AVPV nucleus and GnRH in POA in females, and might induce disruption of the LH surge, consequently disrupting estrous cyclicity and fertility, leading to lower rates of pregnancy and number of fetuses.

Caracterizar física y químicamente las arcillas utilizadas en la preparación de pastas cerámicas para la producción de los lotes de ladrillo tipo H-10 en la empresa Ladrillera Valledupar S.A.S. Para el cumplimiento de los objetivos de la investigación se llevó a cabo una fase de revisión documental en las diferentes bases de datos científicas; posteriormente una etapa de campo, donde se realizaron seis (6) apiques, se recolectaron cinco (5) muestras. A tres (3) de las muestras (A2-C1 Arcilla (N) Negra, A4-C1 Arcilla (T) Tierra y A1-C3 Arcilla (P) Parda) se les aplicaron ensayos de fluorescencia de rayos X (FRX–XRF). Las propiedades físicas fueron evaluadas con el índice de plasticidad de Attenberg, mediante cazuela Casagrande, kit para determinar el limite líquido y ensayos de resistencia a la compresión y absorción de agua (NTC 4205-2 / 2009, NTC 4017 / 2018). Se determinó que las arcillas negras y pardas comparten composiciones químicas (Si, Al y Fe), los cuales son predominantes el K, Mg, Ca, Na y Ti, además presentan promedio % absorción de agua de 9.882 a 12.23 y promedio de resistencia a la compresión de 1.748 a 2.334. La composición química de la arcilla tierra A4-C1 por sí sola no es la más apropiada para la fabricación de productos cerámicos, dada sus altas concentraciones de silicio y bajas concentraciones de alúmina que sobrepasan el 70% y recaen en 16% respectivamente.

Multifactorial aetiology defines non-unions, with a biological and a mechanical distortion of the timeline of bone healing. Research on new advances to increase osteogenesis and promote non-union healing is strongly directed towards new forms of cell products. Basic science and research on non-union treatments is needed to compile preclinical data on new treatments. Bone marrow concentration and expanded mesenchymal stromal cells still require extensive clinical research to confirm efficacy in non-union treatment. Solid preclinical studies, precise cell product definition and preparation, and appropriate ethical and regulatory approvals are needed to assess new advanced therapy medicinal products.Cite this article: EFORT Open Rev 2020;5:574-583.

RESUMEN Introducción: La tuberculosis (TBC) genital es una infección relativamente poco frecuente en la mujer. Afecta principalmente a mujeres menores de 40 años, y el motivo de consulta más usual es la esterilidad, de ahí la importancia de su diagnóstico precoz. Caso clínico: Se presenta el caso de una paciente con dolor pélvico crónico que acude a nuestras consultas para valoración. Durante el estudio se toma biopsia dirigida de la cavidad endometrial diagnosticándose la presencia de granulomas no necrotizantes. Posteriormente se realiza un cultivo microbiológico que resulta positivo para micobacterias y se determina el DNA, mediante reacción en cadena de la polimerasa, de mycobacterium tuberculosis, como causante del cuadro. Discusión: El diagnóstico definitivo de TBC requiere el aislamiento en cultivo del bacilo de Koch, aunque en los casos de TBC genital, al ser una entidad paucibacilar, puede no resultar positivo. En éste caso, sería suficiente el diagnóstico de presunción basado en la sospecha clínica y el hallazgo histológico de granulomas. Conclusión: La tuberculosis genital es una entidad poco frecuente en nuestro medio, aunque es una causa importante de infertilidad femenina y su predominio generalmente se subestima debido a la naturaleza paucisintomática de la misma. El diagnóstico temprano y el tratamiento multidisciplinar son fundamentales.

By 2012, around 170 of the 653 aquifers existing in Mexico were being overexploited, and five of those had been declared on the verge of extinction, thus jeopardizing the sustainability of their regions’ development. This paper reports the results of a field study, realized in 2016-2017 among 121 agricultural producers of the area of influence of the Tecamachalco Aquifer, which is one of the five ones facing possible extinction, with the objective of ascertaining the extent to which market forces, public policies and the users’ practices contribute (or not) to the sustainability of the Aquifer. It is shown that the users and the government contribute more to that effect as the former use irrigation water-saving technologies, included as part of the assistance packages offered through the public administration’s water policies of Mexico.

Inflammatory diseases remain critical health problems worldwide. The search for anti-inflammatory drugs is a primary activity in the pharmaceutical industry. Cacalol is a sesquiterpene with anti-inflammatory potential that is isolated from Psacalium decompositum, a medicinal plant with several scientific reports supporting its anti-inflammatory activity. Cacalol acetate (CA) is the most stable form. Nevertheless, the participation of CA in the main signaling pathway associated with inflammation is unknown. Our aim was to study the anti-inflammatory effect of CA and to determine its participation in NF-κB signaling. In TPA-induced edema in mice, CA produced 70.3% inhibition. To elucidate the influence of CA on the NF-κB pathway, RAW 264.7 macrophages were pretreated with CA and then stimulated with LPS, evaluating NF-ΚB activation, IKK phosphorylation, IΚB-α, p65, cytokine expression, and COX-2 release and activity. CA inhibited NF-κB activation and its upstream signaling, decreasing phosphorylation IKB-α and p65 levels. CA also reduced expression and secretion of TNF-α, IL-1β, and IL-6. Additionally, it decreased the activity and expression of COX-2 mRNA. These data support that CA regulates the NF-κB signaling pathway, which might explain, at least in part, its anti-inflammatory effect. CA is a bioactive molecule useful for the development of anti-inflammatory agents with innovative mechanisms of action.

Objective To determine the management of dyslipidemia in primary care after the publication of the American College of Cardiology/American Heart Association (ACC/AHA) 2013 guidelines and Valencian government's algorithm. Method We conducted a cross-sectional descriptive study that employed a survey of primary care physicians of the Community of Valencia between January and October 2016. Results A total of 199 physicians (mean age, 48.9 ± 11.0 years; experience, 21.3 ± 11.1 years) participated in the survey. The most followed guidelines were those of the European Society of Cardiology (37.5% of respondents) and Valencian government (23.4% of respondents). Some 6.3% of the respondents followed the 2013 ACC/AHA guidelines, and 88.0% established objectives based on LDL cholesterol and cardiovascular risk. The choice of lipid-lowering drug was based on its LDL cholesterol lowering capacity (28.6% of respondents), on the Valencian government's algorithm (23.4%) and on the drug's safety (20.4%). Statins, ezetimibe and fibrates were the preferred hypolipemiant agents, and their combination (51% of respondents) and dosage increases (35%) were the strategies employed for poor control. Lipid profile and transaminase and creatine kinase levels were measured every 6 (59.5%, 52.3% and 54.3% of respondents, respectively) or 12 months (25.1%, 29.2% and 30.3%, respectively). Forty-one percent of the respondents were aware of the controversy surrounding the 2013 ACC/AHA guidelines. Although 60% of the respondents acknowledged its relevance, only 21% changed their daily practices accordingly. Conclusions The Valencian government's algorithm had a greater impact than the 2013 ACC/AHA guidelines in primary care in Valencia. Areas for improvement included the low use of validated guidelines and risk tables and the streamlining of laboratory test periodicity.

Metodo Estudio transversal descriptivo con encuesta a medicos de atencion primaria de la Comunidad Valenciana entre enero y octubre de 2016. Resultados Participaron 199 facultativos con una media (desviacion tipica) de 48,9 (11) anos de edad y 21,3 (11,1) anos de experiencia. Las guias mas seguidas eran las de la European Society of Cardiology (37,5%) y las de la Administracion (23,4%). El 6,3% seguia la de la ACC/AHA 2013. El 88% establecia objetivos segun colesterol LDL y riesgo cardiovascular. La eleccion del hipolipemiante estaba basada en su capacidad reductora de colesterol LDL (28,6%), algoritmo de la Administracion (23,4%) y seguridad (20,4%). Estatinas, ezetimiba y fibratos eran los hipolipemiantes preferidos, y la combinacion (51%) e incremento de dosis (35%) las estrategias en ausencia de control. Se determinaba perfil lipidico, transaminasas y creatincinasa cada 6 (59,5; 52,3 y 54,3%, respectivamente) o 12 meses (25,1; 29,2 y 30,3%, respectivamente). Un 41% era conocedor de la polemica con la Guia ACC/AHA 2013, y aunque un 60% reconocia su relevancia, solo un 21% modifico su quehacer diario por ella. Conclusiones El algoritmo de la Administracion tuvo mayor impacto que la Guia ACC/AHA 2013 en atencion primaria. Campos de mejora fueron el bajo uso de guias y tablas de riesgo validadas, y racionalizacion de la periodicidad de las analiticas.

Introduction Toxoplasma gondii infections have been reported for many warm-blooded animals around the world including chiropterans. However, in Colombia, the country that holds the highest taxonomic richness of this order of mammals in the Neotropics, up to date there are no reports of T. gondii in bats (Carollia brevicauda). Purpose The objective of the present study was to detect T. gondii DNA from internal bat organs from Quindío, Colombia. Results We report the first detection of T. gondii DNA from internal bat organs in the department of Quindio, Central Andes of Colombia. Out of three silky short tail bat (Carollia brevicauda) specimens collected at the natural reserve “La Montaña del Ocaso”, organs were recovered (lungs, liver, heart, kidneys, small and large intestine) and tested for T. gondii through PCR for B1 sequence, with 1/3 (33.3%) positive result for the presence of T. gondii DNA in bat kidney tissues. Conclusion Taking into consideration the high diversity of bat species in Colombia, and the complexity of the ecological and functional relationships that these organisms establish in the ecosystems they inhabit, we discuss on the urgent need for more detailed research and surveys for Toxoplansma in bats and other mammalian wild species.

Objectives Overall, 25% to 33% of patients on kidney transplant wait lists present with prior graft loss. In addition, the number of patients who require a retransplant seems to be increasing. Here, we describe our experience with patients who had a second kidney transplant after a previous pancreas-kidney transplant or a third or fourth kidney transplant. We focused specifically on the technical aspects and outcomes related to this patient group. Materials and methods A single-center retrospective study was performed. The cohortincluded 15 patients > 18 years old who had received a second kidney graft after pancreas-kidney transplant or a second or greater kidney graft between 2013 and 2019. Results Median age of recipients was 45 years (range, 20-58 y). In 10 patients, the transperitoneal approach was selected. In 5 patients, the retroperitoneal heterotopic kidney retransplant technique was used. Early surgical complications (≤ 30 days posttransplant) were reported in 4 patients. Three patients had late ureteral stenosis (> 90 days posttransplant). All grafts were functioning at time of patient discharge. Mean creatinine level was 2.69 mg/dL (range, 1.23-6.26 mg/dL). The 1-year and 2-year graft survivalrates were 85% and 75%, respectively. No grafts were lost because of surgical complications. Conclusions Retransplant of a second graft after pancreas-kidney transplant or retransplant of a third or fourth renal graft is challenging but feasible, with evidence of reasonably positive outcomes after retransplant.

Artículo con numerosos autores, sólo se recogen el primero y los pertenecientes a la UAM, Background and study aim: Advanced therapy medicinal products (ATMP) frequently lack of clinical data on efficacy to substantiate a future clinical use. This study aims to evaluate the efficacy to heal long bone delayed unions and non-unions, as secondary objective of the EudraCT 2011-005441-13 clinical trial, through clinical and radiological bone consolidation at 3, 6 and 12 months of follow-up, with subgroup analysis of affected bone, gender, tobacco use, and time since the original fracture. Patients and methods: Twenty-eight patients were recruited and surgically treated with autologous bone marrow derived mesenchymal stromal cells expanded under Good Manufacturing Practices, combined to bioceramics in the surgical room before implantation. Mean age was 39 ±13 years, 57% were males, and mean Body Mass Index 27 ±7. Thirteen (46%) were active smokers. There were 11 femoral, 4 humeral, and 13 tibial non-unions. Initial fracture occurred at a mean ±SD of 27.9 ±31.2 months before recruit- ment. Efficacy results were expressed by clinical consolidation (no or mild pain if values under 30 in VAS scale), and by radiological consolidation with a REBORNE score over 11/16 points (value of or above 0.6875). Means were statistically compared and mixed models for repeated measurements estimated the mean and confidence intervals (95%) of the REBORNE Bone Healing scale. Clinical and radiological con- solidation were analyzed in the subgroups with Spearman correlation tests (adjusted by Bonferroni). Results: Clinical consolidation was earlier confirmed, while radiological consolidation at 3 months was 25.0% (7/28 cases), at 6 months 67.8% (19/28 cases), and at 12 months, 92.8% (26/28 cases including the drop-out extrapolation of two failures). Bone biopsies confirmed bone formation surrounding the bioce- ramic granules. All locations showed similar consolidation, although this was delayed in tibial non-unions. No significant gender difference was found in 12-month consolidation (95% confidence). Higher consoli- dation scale values were seen in non-smoking patients at 6 ( p = 0.012, t -test) and 12 months ( p = 0.011, t -test). Longer time elapsed after the initial fracture did not preclude the occurrence of consolidation. Conclusion: Bone consolidation was efficaciously obtained with the studied expanded hBM-MSCs com- bined to biomaterials, by clinical and radiological evaluation, and confirmed by bone biopsies, with lower consolidation scores in smokers, This research received funding from the European Union’s Sev- enth Framework Programme ( FP7/FP7-HEALTH-2009 ) with the RE- BORNE Project (under G.A. 241876), and the European Union’s Horizon 2020 Programme ( H2020-SC1 2016-2017 ), with the OR- THOUNION Project (under G.A. 7333288)

El artículo resume la posición o rol de la mujer en el confucionismo clásico. Parte de los textos clásicos del conficionismo, buscando elementos entresacados de los textos que den pistas de la concepción y trato de la mujer. El confucionismo como filosofía práctica se convierte en una doctrina ética fundada fuertemente en la virtud, con miras a mejorar al hombre individual y a la sociedad en su conjunto. La virtud es el eje de las acciones del individuo y del Estado. En el Libro de los Ritos se describen detalles del rol de la mujer en la sociedad, el cual prácticamente se reduce a su papel de esposa y madre. La subordinación de la mujer hacia el hombre en su toma de decisiones queda claramente establecido en los textos. En conclusión, en el confucionismo la relación de parentesco es la que logra el género de la mujer. Aunque, al igual que para el catolicismo, ambos sexos son complementarios.

Resumen Introduccion y objetivos La estrategia Life's Simple 7 de la American Heart Association propuso 7 metricas de salud cardiovascular ideal: indice de masa corporal (IMC) Metodos La metrica de dieta saludable se definio como alcanzar al menos 9 puntos en una escala validada de 14 puntos de adhesion a dieta mediterranea. Se definio evento cardiovascular mayor incidente como infarto de miocardio, ictus o muerte de causa cardiovascular. Se uso regresion de Cox para estimar hazard ratios (HR) ajustadas multivariables con intervalos de confianza del 95% (IC95%) para categorias sucesivas de metricas de salud cardiovascular. Resultados Tras seguir a 7.447 participantes durante una mediana de 4,8 anos, se registraron 288 eventos. Respecto a los participantes con solo 0-1 metricas, tras ajustar por edad, sexo, centro y grupo de intervencion, se observaron HR (IC95%) 0,73 (0,54-0,99), 0,57 (0,41-0,78) y 0,34 (0,21-0,53), para 2, 3 y 4 o mas metricas respectivamente. Conclusiones En una poblacion espanola con alto riesgo cardiovascular, la presencia de un mayor numero de metricas se asocio progresivamente con una reduccion sustancial en la tasa de eventos cardiovasculares mayores.

The 15th edition of the Workshop on Recent Issues in Bioanalysis (15th WRIB) was held on 27 September to 1 October 2021. Even with a last-minute move from in-person to virtual, an overwhelmingly high number of nearly 900 professionals representing pharma and biotech companies, contract research organizations (CROs), and multiple regulatory agencies still eagerly convened to actively discuss the most current topics of interest in bioanalysis. The 15th WRIB included three Main Workshops and seven Specialized Workshops that together spanned 1 week in order to allow exhaustive and thorough coverage of all major issues in bioanalysis, biomarkers, immunogenicity, gene therapy, cell therapy and vaccines. Moreover, in-depth workshops on biomarker assay development and validation (BAV) (focused on clarifying the confusion created by the increased use of the term "context of use" [COU]); mass spectrometry of proteins (therapeutic, biomarker and transgene); state-of-the-art cytometry innovation and validation; and critical reagent and positive control generation were the special features of the 15th edition. This 2021 White Paper encompasses recommendations emerging from the extensive discussions held during the workshop, and is aimed to provide the bioanalytical community with key information and practical solutions on topics and issues addressed, in an effort to enable advances in scientific excellence, improved quality and better regulatory compliance. Due to its length, the 2021 edition of this comprehensive White Paper has been divided into three parts for editorial reasons. This publication (Part 2) covers the recommendations on ISR for Biomarkers, Liquid Biopsies, Spectral Cytometry, Inhalation/OralMultispecific Biotherapeutics, Accuracy/LLOQ for Flow Cytometry. Part 1A (Endogenous Compounds, Small Molecules, Complex Methods, Regulated Mass Spec of Large Molecules, Small Molecule, PoC), Part 1B (Regulatory Agencies' Inputs on Bioanalysis, Biomarkers, Immunogenicity, GeneCell Therapy and Vaccine) and Part 3 (TAb/NAb, Viral Vector CDx, Shedding Assays; CRISPR/Cas9CAR-T Immunogenicity; PCRVaccine Assay Performance; ADA Assay ComparabilityCut Point Appropriateness) are published in volume 14 of Bioanalysis, issues 9 and 11 (2022), respectively.

Six- and seven-membered ring-fused, functionalized cyclopentadienes can be obtained in moderate to excellent yields by a cascade process entailing the Au(I)-catalyzed propargyl Claisen rearrangement/Nazarov cyclization of propargyl vinyl ethers, the hetero-Diels-Alder reaction with dialkylazodicarboxylates, and the spontaneous conversion of cycloaddition products into cyclopentadienes by a highly regioselective cleavage of a C-N bond. Depending on the treatment of the crude reaction mixtures, two types of products can be obtained: cyclopentadienes with pendant hydrazine and aldehyde moieties that intramolecularly react to form hemiaminals are obtained in 43-52% overall yields when the crude reaction mixtures are left over K

PSA is the most widely used diagnosticand prognostic biomarker in prostate cancer (PCa).However, its lack of specificity has generated the needto search for new complementary markers. In thisscenario, blood plasma constitutes one of the sourcesof search for new markers, which have been tried tobe combined with PSA and other clinical variables inorder to develop tests that increase their diagnosticspecificity.This narrative review of the literature provides anoverview of commercially available plasma biomarkers and tests for use in different clinical settingsfor PCa. The most studied markers to help select theappropriate patients for initial and / or repeat biopsyhave been: PHI, 4K, STHLM3. These markers havebeen oriented towards the diagnosis of the so-calledclinically signifi cant PCa, trying to validate and calibratetheir algorithms in different populations. Giventhe development and evolution in the diagnosis of PCa,there is still a lack of evidence of the impact of magneticresonance imaging (MRI) when used in combinationwith these new markers, as well as its possiblerole in the screening of the disease and not only in theearly diagnosis process. Furthermore, there are only asmall number of studies that have directly comparedthese tests with each other and with PSA, so there isnot enough evidence to know which test has the bestproperties in each clinical scenario. In order to clarifythe true diagnostic role of these new biomarkers, newprospective, comparative studies in different populationsare absolutely necessary to evaluate their clinicalutility in combination with MRI and fusion biopsy.El PSA es el biomarcador diagnóstico ypronóstico más ampliamente utilizado en cáncer deprostata (CaP). Sin embargo, su falta de especificidadha generado la necesidad de buscar nuevos marcadorescomplementarios. En este escenario, el plasmasanguíneo constituye una de las fuentes de búsquedade nuevos marcadores, los cuales han tratado decombinarse con el PSA y otras variables clínicas conel objeto de desarrollar tests que aumentaran su especificidaddiagnóstica.En esta revisión narrativa de la literatura se proporcionauna descripción general de los biomarcadoresplasmáticos y tests disponibles comercialmentepara ser utilizados en diferentes contextos clínicosdel CaP. Los test más estudiados para ayudar a seleccionarlos pacientes adecuados para la biopsia inicialy / o repetida han sido: PHI, 4K, STHLM3. Estos testse han orientado hacia el diagnóstico del denominadoCaP clínicamente significativo, intentando validary calibrar sus algoritmos en diferentes poblaciones.Dado el desarrollo y evolución en el diagnóstico deCaP, aún existe una falta de evidencia del impacto de la resonancia magnética (RM) al ser empleada encombinación con estos nuevos marcadores, así comosu posible papel en el screening de la enfermedad yno solo en el proceso de diagnóstico precoz. Además,solo se dispone de una pequeña cantidad de estudiosque hayan comparado directamente estos test entreellos y con el PSA, de modo que no existe evidenciasuficiente para saber qué test tiene mejores propiedadesen cada escenario clínico. En el escenarioactual, para poder aclarar el verdadero papel diagnósticode estos nuevos biomarcadores, son absolutamentenecesarios nuevos estudios prospectivos,comparativos y en diferentes poblaciones, que evalúensu utilidad clínica en combinación con la RM yla biopsia fusión.

Resumen Introducción. Toxoplasma gondii es un parásito con gran potencial zoonótico que puede infectar un amplio rango de huéspedes de sangre caliente, incluidos los animales del sector pecuario, lo que causa pérdidas a la industria. En el humano, es patógeno en personas inmunosuprimidas y afecta el desarrollo del feto en infecciones congénitas. Además, se asocia con diversos trastornos del comportamiento en personas sanas. El humano puede adquirir T. gondii al consumir carnes contaminadas mal cocidas. Objetivo. Determinar la positividad de T. gondii en carnes de consumo humano (res, pollo y cerdo) en Ibagué, Colombia. Materiales y métodos. Se utilizó la PCR convencional anidada y la secuencia del gen B1 de T. gondii como blanco de amplificación. Se tomaron 186 muestras de carne comercializada en la zona urbana de Ibagué (62 de res, 62 de pollo y 62 de cerdo) y se obtuvo el porcentaje de positividad en cada tipo de carne evaluada. Resultados. Se encontró un porcentaje de positividad de 18,8 % en las muestras, siendo la carne de cerdo la del mayor porcentaje (22,5 %; 14/62), seguida por las muestras de carne de res (19,3 %; 12/62) y de pollo (14,5 %; 9/62). Los mejores productos amplificados fueron secuenciados en Macrogen, y alineados con las secuencias del gen B1 depositadas en el GenBank, con lo que se confirmó su identidad. Conclusiones. Este es el primer estudio sobre prevalencia de T. gondii en carnes para consumo humano en Ibagué y el departamento del Tolima. Se demostró que los tres tipos de carne representan un riesgo para la infección en humanos a nivel local. Abstract Introduction: Toxoplasma gondii is a parasite with great zoonotic potential. It can infect a broad range of warm-blooded hosts (including livestock) and causes significant losses in the industry. In humans, it has been described as a pathogen in immunosuppressed people, it affects the fetus development in congenital infections, and is associated with various behavioral disorders in healthy people. Humans can acquire T. gondii by consuming undercooked, contaminated meat. Objective: To determine T. gondii positivity (currently unknown) in meat for human consumption (i.e., beef, chicken, and pork) in the city of Ibague, Colombia. Materials and methods: We used conventional nested PCR and the T. gondii B1 gene sequence as amplification target. We collected samples of meat (N=186) sold in the urban area of Ibagué (62 beef, 62 chicken, and 62 pork samples) and determined the T. gondii positivity percentage for each type of meat. Results: The study found an average of 18.8% positivity for all meat samples, pork having the highest percentage (22.5%; 14/62), followed by beef (19.3%; 12/62) and chicken (14.5%; 9/62). The best-amplified products were sequenced by macrogen and aligned with the B1 gene sequences in GenBank, thereby confirming their identity. Conclusions: This is the first study of T. gondii prevalence in meat for human consumption carried out in the city of Ibagué and the department of Tolima. All three types of meat sampled represent a risk for local human infection.

INTRODUCTION: Activated Tregs in the tumor micro-environment are correlated with poor outcomes, and are considered as key players in tumor immune-escape. So far, Treg depletion has not been successful in patients, either because adequate Treg depletion was not achieved or because Teff cells have either been impacted or depleted as well. RG6292 is the first anti-human CD25 antibody developed to specifically deplete human Tregs while preserving IL-2R STAT5 signaling and Teff activity. It has been optimized for ADCC and selective depletion of cells with high CD25 density (Treg). MATERIALS and METHODS: Adult patients with advanced solid tumors were given RG6292 i.v. Q3W as monotherapy (S1: NCT04158583) or in combination with atezolizumab 1200 mg Q3W (S2: NCT04642365) in a Ph1 dose escalation study. 76 pts have been treated at dose levels ranging from 0.3 mg to 165 mg in S1 and 48 pts at dose levels ranging from 0.3 mg to 160 mg in S2. In both studies a Bayesian logistic regression model with overdose control guided dose escalation was utilized. Data cutoff was May 27, 2022. Pharmacokinetic and pharmacodynamic analyses were undertaken in peripheral blood and tumor tissue. PK/PD modeling applied to Treg and Teff cells helped characterize and identify the optimal therapeutic window to ensure (1) relevant Treg depletion and (2) limited impact on T effector. RESULTS: RG6292 has a linear and time independent PK with no ADA detected. A Population PK-PD modeling approach was applied to Treg and Teff cells in the periphery. To predict the RG6292 effects in the tumor microenvironment (TME), the PK/PD relationships observed and characterized in the periphery for all cell subpopulations were considered the same, a tumor uptake factor of 15% was considered. At steady-state trough, a 70 mg Q3W dose was predicted to lead to 72% of patients with concentration above the Treg (%CD4) EC50 in tumor and 40% of patients with concentration above the Non-Treg (%CD4) EC50 in plasma. RG6292 induced a dose-dependent peripheral and intratumoral Treg depletion in on-treatment biopsies taken 28 days after initiation of treatment. Treatment did not appear to impact the number nor the functionality of intratumoral CD8 T cells nor any evident effect observed on PDL1 expression. In blood, stable levels of all other immune cells were observed after treatment. Moreover, in both studies a marginal increase of IFNg, CXCL10, IL-10, TNF was observed. No consistent gene expression alterations nor immune signatures could be observed when comparing BSL vs OT biopsies in S1. CONCLUSION: RG6292, consistent with its proposed mechanism of action, induces profound and preferential depletion of Treg cells over CD8+CD25+ in the periphery and in the TME at clinically safe doses between 35-70mg. Further development of RG6292 is currently being explored.

El presente trabajo tiene el objetivo de resignificar las operaciones matemáticas de los productos notables y la factorización con procedimientos geométricos y razonamiento lógico matemático, de tal manera que los estudiantes vean las operaciones como inversas una de otra y esto les permita transitar matemáticamente con mayor facilidad. Este contenido matemático se estudia en el tercer grado de educación telesecundaria, en el primer bloque del programa. Para aplicar las actividades didácticas, se rescataron los conocimientos previos de los estudiantes, lo cual les permitió construir con mayor facilidad las reglas para el desarrollo de los productos notables como es el caso de los binomios cuadrados, conjugados y binomios con un término común; posteriormente, se realizaron las actividades inversas, es decir, pasar de un trinomio cuadrado perfecto a un binomio cuadrado y a sí sucesivamente con los otros dos productos notables. En cuanto a los resultados obtenidos por la implementación de las secuencias didácticas, 17 alumnos (85 %) tuvieron un mejor aprovechamiento escolar. En conclusión, los alumnos pudieron relacionar las operaciones en forma retrospectiva hasta llegar al punto de partida; este razonamiento casi desperdiciado en la enseñanza de la matemática permite apropiarse de la resolución de problemas con su respectiva comprobación, eso quiere decir que existe un aprendizaje con un razonamiento metacognitivo. Las únicas dificultades que se observaron en el aprendizaje se presentaron en la representación gráfica de los binomios conjugados y en la construcción de la regla de los binomios con un término común.

In this paper, we present an unprecedented and general umpolung protocol that allows the functionalization of silyl enol ethers and of 1,3-dicarbonyl compounds with a large range of heteroatomic nucleophiles, including carboxylic acids, alcohols, primary and secondary amines, azide, thiols, and also anionic carbamates derived from CO2. The scope of the reaction also extends to carbon-based nucleophiles. The reaction relies on the use of 1-bromo-3,3-dimethyl-1,3-dihydro-1delta3[d][1,2]iodaoxole, which provides a key alpha-brominated carbonyl intermediate. The reaction mechanism has been studied experimentaly and by DFT, and we propose formation of an unusual enolonium intermediate with a halogen-bonded bromide.

The irradiation of (Z)-2-phenyl-4-aryliden-5(4H)-oxazolones 1 in deoxygenated CH2Cl2 at 25 °C with blue light (465 nm) in the presence of [Ru(bpy)3](BF4)2 (5% mole ratio) as a triplet photocatalyst promotes the [2+2] photocycloaddition of the C═C bonds of the 4-arylidene moiety, thus allowing the completely regio- and stereoselective formation of cyclobutane-bis(oxazolone)s 2 as single stereoisomers. Cyclobutanes 2 have been unambiguously characterized as the μ-isomers and contain two E-oxazolones coupled in an anti-head-to-head form. The use of continuous-flow techniques in microreactors allows the synthesis of cyclobutanes 2 in only 60 min, compared with the 24–48 h required in batch mode. Ring opening of the oxazolone heterocycle in 2 with a base affords the corresponding 1,2-diaminotruxinic bis-amino esters 3, which are also obtained selectively as μ-isomers. The ruthenium complex behaves as a triplet photocatalyst, generating the reactive excited state of the oxazolone via an energy-transfer process. This reactive excited state has been characterized as a triplet diradical 3(E/Z)-1* by laser flash photolysis (transient absorption spectroscopy). This technique also shows that this excited state is the same when starting from either (Z)- or (E)-oxazolones. Density functional theory calculations show that the first step of the [2+2] cycloaddition between 3(E/Z)-1* and (Z)-1 is formation of the C(H)–C(H) bond and that (Z) to (E) isomerization takes place at the 1,4-diradical thus formed., The authors thank the Spanish Government for funding: Project PID2020-119636GB-I00, funded by MCIN/AEI/10.13039/501100011033; Projects PID2019-106394GB-I00/AEI/10.13039/501100011033, PID2019-110441RB-C33/AEI/10.13039/501100011033, and PID2019-110008GB-I00/AEI/10.13039/501100011033, funded by MCIN/AEI/10.13039/501100011033; Projects RTI2018-101784-B-I00, RTI2018-101033-B-I00, and CTQ2017-84825-R, funded by MCIN/AEI/10.13039/501100011033 and FEDER Una manera de hacer Europa.

The main purpose of this observational prospective pilot study was to evaluate the effects of hydrolysed collagen supplementation, in endurance training, in the performance of runners. A cohort of sixty-one subjects (women with an age = 44 ± 5 years; height = 1.65 ± 0.4 m; weight = 58.4 ± 5.2 kg; men with an age = 51 ± 3 years; height = 1.82 ± 0.2 m; weight = 74.4 ± 3.1 kg) received a collagen supplement (11 g / day) during 16 weeks. They performed a 21 kilometre endurance test (21KmET) at baseline and after 16 weeks of follow up. Squat Jump (SJ) and Counter Movement Jump (CMJ) tests were measured before and after each 21KmET and biochemical analyses and a bioimpedance were performed after each 21KmET. Subjects underwent three sport training sessions a week and a supplement intake during the follow up. Regarding the 21KmET time, there were significant differences between before and after supplementation intake (p < .05) and a higher pain perception was assessed with a visual analogue scale at the second 21KmET (p < .05). Significant improvements were observed in handgrip strength, SJ and CMJ after 16 week of supplement intake. Conclusions: A programmed endurance training improves the functionality of the runner in long-distance events and a periodic intake of hydrolysed collagen could help a better performance because it improves the conditions of muscles and joints.
