The coupled model is discretized using a positivity preserving second-order path-conservative finite volume scheme. Then, the data assimilation problem is posed in a global optimization framework. Later, multi-path parallel metaheuristic stochastic global optimization algorithms are developed. More precisely, a multi-path Simulated Annealing algorithm is compared with a multi-path hybrid global optimization algorithm based on coupling Simulated Annealing with gradient local searchers.The authors want to acknowledge the designers of the experiment [83] , for making the data publicly available.

Evaluación de indicadores de bienestar animal de bovinos en un rastro Tipo Inspección Federal

The slaughter process is the last stage of management and represents a point at which the welfare of the cattle is compromised. The objective of this study was to evaluate the animal welfare indicators of cattle in a Federal Inspection Type slaughterhouse. The slaughter process of 1,167 animals [740 males (63.8 %) and 420 females (36.2 %)] was observed in a Federal Inspection Type slaughter plant in northwestern Mexico. Management and behavioral variables, as well as indicators of return to sensitivity were recorded, and the bruises observed on the carcasses were characterized. 10 % of the cattle received electric shocks with prods, while 24.2 % were beaten by operators. Arching of the spine was observed (44.5 %), 62.2 % of the animals exhibited sensitivity during exsanguination. The prevalence of bruising was 88.8 %. Females had 1.62 % higher risk of bruising than males and the presence of large horns increased the risk of bruising by 1.46 %. The characteristics of the bruises observed were bright red (93.8 %), mottled (71.5 %), small (82.9 %), and grade 1 (95.7 %). The area most affected by bruises was the dorsal-lumbar area, with 58.3 %. It was concluded that the animals included in this study were exposed to conditions conducive to stress, including the use of the electric prod by the operators, undesirable behaviors of cattle during herding, ineffective stunning, and the presence of bruises on the carcasses.El proceso de sacrificio es la última etapa de manejo y representa un punto en el que se compromete el bienestar de los bovinos. El objetivo del presente trabajo fue evaluar los indicadores de bienestar animal de bovinos en un rastro Tipo Inspección Federal. Se observó el proceso de sacrificio de 1,167 animales [740 machos (63.8 %) y 420 hembras (36.2 %)] en una planta de sacrificio Tipo Inspección Federal en el noroeste de México. Se registraron variables de manejo y comportamiento, así como indicadores de retorno a la sensibilidad y se caracterizaron los hematomas observados en las canales. El 10 % del ganado recibió descargas eléctricas con picanas, el 24.3 % fue golpeado por los operarios. Se observó arqueamiento de la columna vertebral (44.5 %), el 62.2 % de los animales mostró sensibilidad durante el sangrado. La prevalencia de hematomas fue del 88.8 %. Las hembras tuvieron 1.62 mayor riesgo de sufrir hematomas que los machos y la presencia de cuernos grandes incrementó el riesgo de presentar hematomas 1.46. Las características de los hematomas observados fueron rojo brillante (93.8 %), moteado (71.5 %), pequeño (82.9 %) y grado 1 (95.7 %). La zona más afectada por hematomas fue la dorso-lumbar con un 58.3 %. Se concluyó que los animales incluidos en el presente estudio estuvieron expuestos a condiciones que propician el estrés, entre estos, el uso de la picana eléctrica por los operarios, las conductas indeseables de los bovinos durante el arreo, el aturdimiento ineficaz y la presencia de hematomas en las canales

POLLEN PROFILE OF PROPOLIS PRODUCED ON THE EASTERN EDGE OF THE SONORAN DESERT IN CENTRAL SONORA, MEXICO

ABSTRACT Eight propolis samples from the eastern edge of the Sonoran Desert were collected at two sites (Pueblo de Álamos and Rancho Viejo, located at Ures, Sonora, Mexico) during two seasons of the year (winter and summer, 2012 and 2013) and analyzed using palynological methods in order to determine which plants were visited by bees in order to collect raw material (resins, wax and pollen) to form propolis. The pollen analysis identified a total of 42 pollen types. Six samples of propolis were bifloral (summer and winter samples) and two multifloral (winter). Mimosa distachya var. laxiflora and Prosopis velutina were considered characteristic pollen types, composing 15 to 45% of total pollen sums

Influence of non-osteoporotic treatments in patients on active anti-osteoporotic therapy: evidence from the OSTEOMED registry

Producción CientíficaPurpose To evaluate the effect of different non-osteoporotic drugs on the increase or decrease in the risk of incident fragility fractures (vertebral, humerus or hip) in a cohort of patients diagnosed with osteoporosis on active anti-osteoporotic therapy. Methods For this retrospective longitudinal study, baseline and follow-up data on prescribed non-osteoporotic treatments and the occurrence of vertebral, humerus or hip fractures in 993 patients from the OSTEOMED registry were analyzed using logistic regression models. The drugs evaluated with a possible beneficial effect were thiazides and statins, while the drugs evaluated with a possible harmful effect were antiandrogens, aromatase inhibitors, proton pump inhibitors, selective serotonin reuptake inhibitors, benzodiazepines, GnRH agonists, thyroid hormones, and oral and inhaled corticosteroids. Results Logistic regression analyses indicated that no treatment significantly improved fracture risk, with the only treatments that significantly worsened fracture risk being letrozole (OR = 0.18, p-value = 0.03) and oral corticosteroids at doses ≤ 5 mg/ day (OR = 0.16, p-value = 0.03) and > 5 mg/day (OR = 0.27, p-value = 0.04). Conclusion The potential beneficial or detrimental effects of the different drugs evaluated on fracture risk are masked by treatment with anabolic or antiresorptive drugs that have a more potent action on bone metabolism, with two exceptions: letrozole and oral corticosteroids. These findings may have important clinical implications, as patients receiving these treat- ments are not fully protected by bisphosphonates, which may imply the need for more potent anti-osteoporotic drugs such as denosumab or teriparatide.Publicación en abierto financiada por el Consorcio de Bibliotecas Universitarias de Castilla y León (BUCLE), con cargo al Programa Operativo 2014ES16RFOP009 FEDER 2014-2020 DE CASTILLA Y LEÓN, Actuación:20007-CL - Apoyo Consorcio BUCL

Lenalidomide and dexamethasone with or without clarithromycin in patients with multiple myeloma ineligible for autologous transplant: a randomized trial

Although case-control analyses have suggested an additive value with the association of clarithromycin to continuous lenalidomide and dexamethasone (Rd), there are not phase III trials confirming these results. In this phase III trial, 286 patients with MM ineligible for ASCT received Rd with or without clarithromycin until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival (PFS). With a median follow-up of 19 months (range, 0-54), no significant differences in the median PFS were observed between the two arms (C-Rd 23 months, Rd 29 months; HR 0.783, p = 0.14), despite a higher rate of complete response (CR) or better in the C-Rd group (22.6% vs 14.4%, p = 0.048). The most common G3-4 adverse events were neutropenia [12% vs 19%] and infections [30% vs 25%], similar between the two arms; however, the percentage of toxic deaths was higher in the C-Rd group (36/50 [72%] vs 22/40 [55%], p = 0.09). The addition of clarithromycin to Rd in untreated transplant ineligible MM patients does not improve PFS despite increasing the ?CR rate due to the higher number of toxic deaths in the C-Rd arm. Side effects related to overexposure to steroids due to its delayed clearance induced by clarithromycin in this elderly population could explain these results. The trial was registered in clinicaltrials.gov with the name GEM-CLARIDEX: Ld vs BiRd and with the following identifier NCT02575144. The full trial protocol can be accessed from ClinicalTrials.gov.

Risk categories in COVID-19 based on degrees of inflammation: data on more than 17,000 patients from the Spanish SEMI-COVID-19 registry

Background: the inflammation or cytokine storm that accompanies COVID-19 marks the prognosis. This study aimed to identify three risk categories based on inflammatory parameters on admission. Methods: retrospective cohort study of patients diagnosed with COVID-19, collected and followed-up from 1 March to 31 July 2020, from the nationwide Spanish SEMI-COVID-19 Registry. The three categories of low, intermediate, and high risk were determined by taking into consideration the terciles of the total lymphocyte count and the values of C-reactive protein, lactate dehydrogenase, ferritin, and D-dimer taken at the time of admission. Results: a total of 17,122 patients were included in the study. The high-risk group was older (57.9 vs. 64.2 vs. 70.4 years; p < 0.001) and predominantly male (37.5% vs. 46.9% vs. 60.1%; p < 0.001). They had a higher degree of dependence in daily tasks prior to admission (moderate-severe dependency in 10.8% vs. 14.1% vs. 17%; p < 0.001), arterial hypertension (36.9% vs. 45.2% vs. 52.8%; p < 0.001), dyslipidemia (28.4% vs. 37% vs. 40.6%; p < 0.001), diabetes mellitus (11.9% vs. 17.1% vs. 20.5%; p < 0.001), ischemic heart disease (3.7% vs. 6.5% vs. 8.4%; p < 0.001), heart failure (3.4% vs. 5.2% vs. 7.6%; p < 0.001), liver disease (1.1% vs. 3% vs. 3.9%; p = 0.002), chronic renal failure (2.3% vs. 3.6% vs. 6.7%; p < 0.001), cancer (6.5% vs. 7.2% vs. 11.1%; p < 0.001), and chronic obstructive pulmonary disease (5.7% vs. 5.4% vs. 7.1%; p < 0.001). They presented more frequently with fever, dyspnea, and vomiting. These patients more frequently required high flow nasal cannula (3.1% vs. 4.4% vs. 9.7%; p < 0.001), non-invasive mechanical ventilation (0.9% vs. 3% vs. 6.3%; p < 0.001), invasive mechanical ventilation (0.6% vs. 2.7% vs. 8.7%; p < 0.001), and ICU admission (0.9% vs. 3.6% vs. 10.6%; p < 0.001), and had a higher percentage of in-hospital mortality (2.3% vs. 6.2% vs. 23.9%; p < 0.001). The three risk categories proved to be an independent risk factor in multivariate analyses. Conclusion: the present study identifies three risk categories for the requirement of high flow nasal cannula, mechanical ventilation, ICU admission, and in-hospital mortality based on lymphopenia and inflammatory parameters

Flora en playas y dunas costeras de México

Background and Aims: The first updated floristic checklist, supported with herbarium specimens, is presented for beaches and coastal sand dunes of Mexico.Methods: The analysis is based on the revision of 14 national and foreign herbaria. A 2 × 2 km grid was placed over a map of the coastal sand dunes of Mexico to reference the herbarium records, corresponding to the 2180 sites and 12,419 examples of plants documented. Indices of diversity, similarity, taxonomic diversity, and redundancy were calculated.Key results: The flora of the beaches and coastal sand dunes of Mexico consists of 153 families, 897 genera, and 2075 species of vascular plants. These represent 9.5% of the vascular flora of Mexico. The herbaria with high indices of redundancy (IR≥0.7) are the herbarium of the Universidad Nacional Autónoma de México (IR=0.9), the Centro de Investigación Científica de Yucatán (CICY, IR=0.8), the Centro de Investigaciones Biológicas del Noroeste (HCIB), the Instituto de Ecología, A.C. (XAL) and the Natural Museum in San Diego (SD), each with an IR of 0.7. Five floristic regions are clearly recognized, which correspond to the seas of Mexico. The North Pacific has the highest taxonomic diversity and the South Pacific has the least. The Gulf of California, Gulf of Mexico and the Caribbean Sea have very similar taxonomic diversity. The species with the most recorded occurrences are Trianthema portulacastrum (165), Croton punctatus (107), Echites umbellatus (106) and Ipomoea pes-caprae (90). Considering the ecotonal nature of the ecosystem, most dune plants are shared with neighboring vegetation (forests, scrubs, wetlands, such as marshes or mangrove swamps).Conclusions: This first checklist of the flora of beaches and coastal dunes is the baseline for multiple future studies: floristic, biogeographic, and ecological. Moreover, this list will be important if used in environmental assessments and coastal zone plans.Antecedentes y Objetivos: Se presenta el primer listado florístico de las playas y dunas costeras de México, actualizado y respaldado por ejemplares de herbario.Métodos: Se revisaron 14 herbarios nacionales y extranjeros. Se sobrepuso una retícula de 2 × 2 km al mapa de la costa y de las dunas costeras de México para referir todos los registros que corresponden a 2180 sitios con 12,419 ejemplares de plantas. Se calcularon índices de diversidad, similitud, diversidad taxonómica y redundancia.Resultados clave: La flora registrada consta de 153 familias, 897 géneros y 2075 especies de plantas vasculares, las cuales representan 9.5% de la flora vascular de México. Las cinco colecciones con índices de redundancia altos IR≥0.7 son los herbarios de la Universidad Nacional Autónoma de México (MEXU, IR=0.9), del Centro de Investigación Científicas de Yucatán (CICY, IR=0.8), y los del Centro de Investigaciones Biológicas del Noroeste (HCIB), el Instituto de Ecología, A.C. (XAL) y el del Museo de Historia Natural de San Diego (SD), cada uno con un IR de 0.7. Se reconocen cinco regiones florísticas que corresponden a los mares de México. El Pacífico Norte tiene mayor diversidad taxonómica y el Pacífico Sur menor diversidad taxonómica. El Golfo de California, Golfo de México y Mar Caribe tienen diversidades taxonómicas similares. Las especies con más registros son Trianthema portulacastrum (165), Croton punctatus (107), Echites umbelllatus (106) e Ipomoea pes-caprae (90). Por el carácter de ecotono de las dunas costeras, la mayoría de las especies se comparten con los tipos de vegetación vecinos (selvas, matorrales, y humedales como las marismas y manglares).Conclusiones: Esta primera lista de la flora en playas y dunas de México es la base para múltiples estudios florísticos regionales y locales, biogeográficos, y ecológicos; además, que será importante para su uso en temas de impacto ambiental y manejo costero

Compromising between European and US allergen immunotherapy schools: Discussions from GUIMIT, the Mexican immunotherapy guidelines

Background: Allergen immunotherapy (AIT) has a longstanding history and still remains the only disease-changing treatment for allergic rhinitis and asthma. Over the years 2 different schools have developed their strategies: the United States (US) and the European. Allergen extracts available in these regions are adapted to local practice. In other parts of the world, extracts from both regions and local ones are commercialized, as in Mexico. Here, local experts developed a national AIT guideline (GUIMIT 2019) searching for compromises between both schools. Methods: Using ADAPTE methodology for transculturizing guidelines and AGREE-II for evaluating guideline quality, GUIMIT selected 3 high-quality Main Reference Guidelines (MRGs): the European Academy of Allergy, Asthma and Immunology (EAACI) guideines, the S2k guideline of various German-speaking medical societies (2014), and the US Practice Parameters on Allergen Immunotherapy 2011. We formulated clinical questions and based responses on the fused evidence available in the MRGs, combined with local possibilities, patient's preference, and costs. We came across several issues on which the MRGs disagreed. These are presented here along with arguments of GUIMIT members to resolve them. GUIMIT (for a complete English version, see Supplementary data) concluded the following: Results: Related to the diagnosis of IgE-mediated respiratory allergy, apart from skin prick testing complementary tests (challenges, in vitro testing and molecular such as species-specific allergens) might be useful in selected cases to inform AIT composition. AIT is indicated in allergic rhinitis and suggested in allergic asthma (once controlled) and IgE-mediated atopic dermatitis. Concerning the correct subcutaneous AIT dose for compounding vials according to the US school: dosing tables and formula are given; up to 4 non-related allergens can be mixed, refraining from mixing high with low protease extracts. When using European extracts: the manufacturer's indications should be followed; in multi-allergic patients 2 simultaneous injections can be given (100% consensus); mixing is discouraged. In Mexico only allergoid tablets are available; based on doses used in all sublingual immunotherapy (SLIT) publications referenced in MRGs, GUIMIT suggests a probable effective dose related to subcutaneous immunotherapy (SCIT) might be: 50–200% of the monthly SCIT dose given daily, maximum mixing 4 allergens. Also, a table with practical suggestions on non-evidence-existing issues, developed with a simplified Delphi method, is added. Finally, dissemination and implementation of guidelines is briefly discussed, explaining how we used online tools for this in Mexico. Conclusions: Countries where European and American AIT extracts are available should adjust AIT according to which school is followed
